Modifying The Stock Exhaust

Hoover2880 · 09-18-2009, 01:31 AM

I noticed alot of people are removing the resonator and the pre-muffler of the exhaust for a slight gain in sound.

I'm curious if anyone has done this but used diffrent mufflers than the oem ones? I know a fellow member on here used flowmaster 40 series I believe and they were to loud he said.

I'm just wanting to cut out the pre muffler replace it with straight pipe and swap the mufflers for something alittle more agressive. Something along the lines of like the Tanabe Touring exhausts.

Any input or suggestions?

Not sure I follow you.. What are you trying to achieve with your exhaust system?

Removing both resonators & then installing different mufflers would be alot of work & it might sound terrible.

Instead of doing all that, I would pick up a used cat back system & try that. You could bolt it in yourself & save all the time spent welding up a system of your own design.

If you just want it louder just try removing 1 or both of the factory resonators as a start.

matching a muffler to a system isn't just about the inlet and outlet diameters, which is why the flow 40 wouldn't sound quite right with a 4 cylinder car; they're designed to be moving 2-4 cylinders worth of air each... A better choice would be a flowmaster 60 Delta, which is the same company but tuned to 4 cylinder use... If you don't know exhausts, don't build your own, just buy a catback. If you do or are willing to learn before hand, then I see no reason why you couldn't throw together a nice system...

FWIW, I see a lot of people saying "go buy a cat back" instead of doing custom exhaust work... I don't agree with this, and I would wager that people think a lot more research has gone into their specific application than it has had in reality... You don't need to be an engineer to know good flow and what can inhibit the cars breathing, but you can't just hack and weld either... Don't go custom to save money, go custom because you want to or need to...

I made a post about this and alot of people have done a decent amount of research on the subject. If you remove the pre-muffler and not the silencer you gain a decent amount of sound without sounding ricey. Check out the post i made there's some great info in there and some sound clips as well. Hope that helps.
