boymeetspavement Posted May 21, 2009 Report Posted May 21, 2009 what sounds the best? I loved the sound of the dynomax superturbo on my ciera, whats your suggestion for the gp 3.1l? Its dual exhaust btw. Quote
meltboy1 Posted May 21, 2009 Report Posted May 21, 2009 just let it rust out, nothin sounds better than a rotted 3.1 exhaust...lol Quote
Night Fury Posted May 21, 2009 Report Posted May 21, 2009 just let it rust out, nothin sounds better than a rotted 3.1 exhaust...lol This man speaks the truth. Very distinctive too! Quote

boymeetspavement Posted May 21, 2009 Author Report Posted May 21, 2009 haha na man I have a baby so i cant have and cabin leakage. Quote
MonteCarloChick Posted May 21, 2009 Report Posted May 21, 2009 Flowmaster? I have one on my 3100 SFI Quote
BXX Posted May 21, 2009 Report Posted May 21, 2009 Flowmaster? I have one on my 3100 SFI I have dual flowmasters and it sounds awsome Quote
boymeetspavement Posted May 21, 2009 Author Report Posted May 21, 2009 They sound nice but its messed up how much they charge for one, 100 bucks for a muffler is retarted. lol I think I spent 50 bucks on the dynomax. Flowmasters do sound good though....lol Quote
MonteCarloChick Posted May 21, 2009 Report Posted May 21, 2009 $100?? I got mine for $70 on Summit. Dynomax BLOWS Quote
RobertISaar Posted May 21, 2009 Report Posted May 21, 2009 i have a cherry bomb glasspack on the monte and soon enough there will be a purple horny on the GP... i like loud... Quote
MonteCarloChick Posted May 21, 2009 Report Posted May 21, 2009 Blah.. glasspacks sound horrid on these cars. Quote
RobertISaar Posted May 21, 2009 Report Posted May 21, 2009 Blah.. glasspacks sound horrid on these cars. on a 3.8 or a 3.4DOHC, i'll agree, but i love the noise of the 3100 with a glasspack. but since boymeetspavement has duals, i don't know how that would sound... Quote
MonteCarloChick Posted May 21, 2009 Report Posted May 21, 2009 It's too raspy. But to each their own Quote
RobertISaar Posted May 21, 2009 Report Posted May 21, 2009 It's too raspy. But to each their own i'm sure there are better options, but for $20, i love the cherry bomb. Quote
Euro Posted May 21, 2009 Report Posted May 21, 2009 I had a Dynomax superturbo on my 3.1 Lumina, and it was too quiet for my liking. Everybody was shocked when I told them I had aftermarket exhaust. 4 years later when the Dynomax rotted out and developed a 4 inch diameter hole...it sounded awesome Quote
oldscsc Posted May 21, 2009 Report Posted May 21, 2009 Are you sure it's true duals, not a Y-pipe? Quote
RobertISaar Posted May 21, 2009 Report Posted May 21, 2009 probably a Y-Pipe, but that will still determine a lot of the characteristics of how it sounds Quote
MonteCarloDude Posted May 21, 2009 Report Posted May 21, 2009 Blah.. glasspacks sound horrid on these cars. x2362152347458 Quote
boymeetspavement Posted May 21, 2009 Author Report Posted May 21, 2009 Yea its y pipe, which isnt looking too good either. Ill get into this project friday before i go on vaca. Quote
johnnymossville Posted May 21, 2009 Report Posted May 21, 2009 Dynomax Super turbos are some of the best mufflers on the market. They flow rate all of their mufflers and they most definitely flow better than Flowmasters but everyone buys their muffs for different reasons. I did extensive research on mufflers before I bought the Dynomax Super Turbos for my build. For the money you cannot buy a better flowing muffler. The whole idea in designing your exh. system is to create a horsepower loss free system whether you want it quiet or loud. lol The size of pipe makes a major difference in the sound of an engine also, bigger means louder than a smaller dia. pipe with the same mufflers on it. Oh and by the way, glass pack mufflers are some of the worst flowing mufflers ever. I mentioned earlier everyone chooses their muffler for a different reason and I personally like something quiet when cruising, loud when accelerating, and something that won't rob my engine of HP. Overkill Engineering Motorsports has nice 2.5" mandrel bent exh. for W-bodies (same as yours or a Z34 Lumina). Quote

johnnymossville Posted May 21, 2009 Report Posted May 21, 2009 ^^^ True enough about the factory muffs but most glass packs have a smaller internal pipe than the size of the ends of the muffler and actually flow less than a similar length of open pipe the same size. Quote
RobertISaar Posted May 21, 2009 Report Posted May 21, 2009 ^^^ True enough about the factory muffs but most glass packs have a smaller internal pipe than the size of the ends of the muffler and actually flow less than a similar length of open pipe the same size. luckily, since glasspacks are straight through, its fairly easy to determine if thats the case, also, i can't remember what size ID/OD mine is, but i just slipped it over the factory tubing where i cut off the stocker, and welded. trust me, if there is restriction in the exhaust, it is certainly not from the glasspack. the cat makes more backpressure than the muffler.

AWeb80 Posted May 21, 2009 Report Posted May 21, 2009 I look forward to hearing some of these exhausts in dayton. i want some, but want to hear some first. my stock with a 2.5 inch dp and no cat sounds pretty good though. Quote
