Well after checking the prices and finding out it will not cost the $600 that i thought it would I have elected to go with cat back replacement (86ing the resognator)instead of glass packs......after all it didnt seem like many of you thought it would be a great idea. The local small muffler shop here is going to do the bends and muff's for $300 cash.....also i have seen his work as he did my Toyota pickup. The question here is basically I have 2 options he has in stock. The "origional" 40 series flowmasters of the magnaflow alumn.....coated ones.......which one will give me the deeper tone? I guess they make a flowmaster delta series 40 that is a bit deeper tone? What do you guys think?.....Like I say tomarrow is it so any input will help.....Thanks..............Grant

magnaflow is better bang for the buck, but flowmaster will give you a deeper exhaust note

no, the three hundred bucks covers the two mufflers, ss piping @ 2.5", and two ss tips very, very close to the stock ones. Cash only price.
Actually , if i wanted to pinch pennies i could buy 2 new flowmasters on ebay for a bit cheaper.......but .....heck i think i am getting an OK deal and supporting my small town muffler man.

How do you know to pick the 40 series and not any of the other series of Flowmaster? Was that series recommended for the Aurora? Does anybody have any sound clips of the 40 series?
Also for MagnaFlow which muffler series?

SupaStealth
do the DynoMax Turbos make the car sound like an Import? I am also considering DynoMax Ultra Flo SS.
Jim what kind of MagnaFlow mufflers do you have? I am mostly concerned with sound quality since i can take about any car in my area right now. I definitly dont want it to sound like an import. I want it to sound like a Trans Am or Corvette. Some real American Muscle!

MpWarrior21,
oh no, my car sounds beautiful, trust me, i get complements everywhere i go, it's nice and deep, it definitely reminds me of the sound of my 64.5 mustang with the 289ci V8(not quite the same, but you get the picture) i was tryin' to restore a few years ago when i was 16.

I had the Flowmaster 40 Series put on my 97 with stainless steel tips. They have a deep, throaty rumble, but not too deep. Sounds great at WOT. 300 bucks isn't a bad price, either. I don't think you can go wrong with either Flowmaster or Dyno's, it's just a matter of personal preference. Good luck.

Jim those do sound very nice. Which kind of magnaflow do you have? MpWarrior21Same that was on my Bonneville (built for F body 3800's) stainless steel...lifetime guaratee  Love it! Steven, I'm sure it will work fine even after they modifiy the Y split (or T split) whatever...dont think it will affect sound to much... |

Post by stevensolds on Dec 11, 2004 15:42:08 GMT -6
no they arent modifying the y-pipe i dont think. just cutting the resonator and installing the super turbo muffler. what i meant was will it still sound awesome even if i dont get the dynomax pipe put in there.

Post by MpWarrior21 on Dec 11, 2004 18:29:48 GMT -6
yeah I'm wondering the same thing. If I should get a different y-pipe or use the stock one. Remember I'm getting a new y-pipe and 2 mufflers from the accident.

Keep it, actually its more of a T-split. I guess we would need a Y-pipe car owner to compare against mine, but the reason the pipe was modified at all was because in muffler inlet is like 1" (  ) so I needed wider pipe to be welded to the existing pipe to handle the dual Maggers. So, its up to you guys and whatever will fit under there. The stock muffs are diagonal, my Maggers run parralel to the length of the car. |

Oh Steven, I have a good vid of my Tach on a hard acceleration to give an idea of the exhaust note at certain RPM...
I will send later tonight to your comcast acct.

Okay..... well here are the results. For anyone that wonders if it makes a difference to get an exhaust job...well trust me it does. Lets say i am just imagining things, because of the cool sound......But if i sit in the car and idle a 2000 you can literaly hear the stock airbox set up screaming....."give me more air". Actually its just a slight sucking sound, nevertheless it wasn't like that before. If i only knew it was only $300 bucks i would have done it along time ago. I thought i read a post somewhere that jim paid $600. You must have bought the prebent cat back kit? Any how, i did go with the flowmasters because the owner of the suggested it. I have no resonator and 2.5 ss pipe all the way thru with the new custom "Y". I guess I need to do the airbox mod next....as i think the car actually needs it. Almost like it is starving for more air (based on the intake noise). Has anyone else did the exhaust first and heard this. Again, it is not running bad at all......just seems like it could use some more air. Thanks again!
BTW.......Do you think a person could gut the airbox all together and buy a cold air intake with the polished tube and cone filter and vent it somehow so that it is a true cold air intake?......Any thoughts??

Agreed
Once you increase the "out" you have to increase the "in'
Refer to intake threads about intakes and opinions on them. Good to see another convert to the performance exhaust world, the Aurora is SO restrictive, you're butt dyno really feels the difference eh?

Thanks jim.....this just keeps getting better and better.....the guy at the muffler shop said it could act funny when starting cold if i dont get more air in........so tomarrow i will do the airbox thing. Did you do the airbox mod with the k&n filter as i plan to do or did you put on a cold air intake with the k&n cone filter? Also... I think i saw you post that you have the resonator on yours still.......From what i understand from the muffler shop is that it is quite restrictive and really just cuts back on interior noise......thus "flow". The cat converter that comes on them supplies sufficient backpressure.

the guy at the muffler shop said it could act funny when starting cold if i dont get more air in I never cease to be amazed at the things people say. How would your exhaust cause your car to need more air at startup? If your intake can't flow enough to start and idle the car, it has some serious deficencies... |

Post by JimW on Dec 11, 2004 22:08:57 GMT -6
There is a lot more air flow now with the exhaust system, I've heard this as well, if the air flow is increased on the way out, its recommended to increase the amount of airflow in, its half assed if you do one thing and not the other. The classic Aurora is horribly restricted both in and out air flow....it makes some sense to me. I highly doubt there will be any major problems at startup though.
As for my intake, its gutted with the stock K&N filter size, the cone intake goes on once I replace the TB. And I left my resonator on, I prefer the quiet idle of a resonator however I do have a high flow cat converter (another recommended mod)

Which flowmaster did you go with??? Original 40 series, 40 series Delta Flow, or the New Super 40 series?
PS: Get a sound clip of your Flowmasters!!!
Thanks

I would like to hear the differences between Corsa, Magnaflow and Flowmaster Hopefully we'll all get to hear them in person in June! I think that'll really be fun. We need to scout out some backroads that we can take each other for rides on... |

well.......got them on sat. morning. I think they sound really good from the outside. Actually closer to jims mpeg than any. I think i may get used to the hummmmm inside while driving down the highway. But the idle and excelleration are great! For whomever asked i went with the flowmaster 40 series "originals", and not the delta series......from what i understand it is sort of between delta series flowmaster and a magnaflow. Magnaflow being the most open of the 3 pipes mentioned. However i went a bit less opened on the mufflers because i removed the "pre muffler" behind the cat converter. In hindsite i think I would have did what jim did....probably would have cut don on the sound inside the car and kept the noise in the back. I did mod the intake and i do not hear the "sucking wind" noise from the intake no more. Noticed the mod to be slightly better in performance, but most noticeable HP came from the new exhaust setup. Man could i feel the difference....never-the-less, air does seem to flow thru the front better now. My car never did start funny prior or since the airbox mod.....was just told it could be a possibility on cold starts. Please no comments.......I do not proclaim to be any type of expert......just here to learn and share a experience or two that may help someone else in thier descision. Thanks for all the great posts.........By the way whats happening in june??
*poof*

By the way whats happening in june?? *poof* Glad you like the Flowmasters! Resonators are typically pretty straight-through in nature. On my car it was slightly offset, but the Corsa is straight-through. I doubt it is much of a bottleneck, but it sure does cut down on cruising resonance, as the name implies. You might consider putting it back. It is possible to get the flow improvement, great sound, and a quiet car while cruising. My car is possibly quieter than stock while cruising. |

Sheesh.....its been a long hard day.......in correction to what i wrote above.........All I did after the exhaust setup was the airbox mod not the intake mod......yet. But that will have till way after christmas.
Also to clarify......jims set (correct me if im wrong jim) He left in his premuffler and "y'd" back to magnaflows. which are a fairly straight thru open muffler. The pre muffler is designed mainly to cut down on noise inside the car. I took mine off and when with the original flows which is not straight thru as it has a "v" shaped baffle inside....and thus i understand isnt quite as loud. As i was saying.....if you were going to have baffles in your exaust......wouldn't it be better to have the under cab and not on the end? I think so , thus would have done it different. If fact i may put a highflow resonator (premuffler) in if i cant get used to the humm noise on at cruising speeds.

) so I needed wider pipe to be welded to the existing pipe to handle the dual Maggers.
