Ive been reading a lot about the Dynomouth exhaust mod, I was originally considering getting a Corsa catback. After finding out more about them both I am leaning towards getting a Dynomouth mod. There is only one remaining thing I dont know, I know there is a hp boost from a Corsa catback but is there any sort of hp boost from a Dynomouth mod or is it basically a noise modification? And if it is just a noise modification shouldnt i just get a cutoff instead?

Find out what a Corsa muffler flows then have a seat while I tell you the muffler in the Dynomouth flows 2200+ cfm. (it couldn't be measured because the machine maxed out at 2200 cfm and the muffler was still flowing)
Now I don't know what the Corsa muffler flows, but here are some other common muffler flow #s:
Borla #40600: 836 cfm
DynoMax Ultra-Flo SS #17263: 1000 cfm
DynoMax Ultra-Flo Welded #17219: 1133 cfm
DynoMax Super Turbo #17733: 410 cfm
Edelbrock #5511: 579 cfm
Edelbrock 304 SS #5560: 640 cfm
Flowmaster #42540: 352 cfm
Flowmaster #62631: 435 cfm
Flowmaster 50 Series: 362 cfm

As for power, yes. I could feel a power increase as soon as it was done. Right now my car dynos 318 rwhp/334 ft lbs with just a lid, dynomouth, and some free mods. 98s are known for 280 rwhp stock...
Anyway, this is just my opinion... I really like it and try to spread the word all I can. The makers of cat-backs have everyone brainwashed to think that they are a 'must have', and they charge through the nose for them.

Thanks Ratio, I think that info has leaned me even more towards getting a Dynomouth setup instead of a Corsa catback. With that extra money I could get the headers I want... Speaking of headers, with long tube headers would a Dynomouth setup become obnoxiously louder? If so what would be suggested to lower the noise without losing the sound?

Headers and ORP are reportedly louder by some folks I know online, I haven't heard it personally. If you are using an ORP I would pick up the part #24219 bullet for a couple bux more. It's a few inches longer for more muffling. If you plan on using cats you could go either way and still sound good I'm sure.
