Straight pipes?

[zZsKyZz]

I'm thinking about doing a side exhaust without cats or mufflers.. Will this hurt performance any? I've heard a bunch of stuff about back pressure, but I don't really see a need for it as for all it's doing is choking the engine and not letting the engine breath properly.. I see it only helping performance by taking the muffler off and I think the side exhaust would look great. I can probably get a shop to just bend it out for me to the side..

Any ideas on if it will help or not?

don't do it. i remember 5.0 mustang mag ran an article awhile back where they dyno'd different mufflers as well as straight pipes. straight pipes lost power. besides that will be really loud with no mufflers and side exhaust. it will be right in your ear. get some cherry bomb type mufflers at least.

take the cats off, but keep mufflers.

When I had my transmission done I only had an H-pipe under my car and it was 'effin loud.. I really liked that sound

Engines DO need backpressure to operate properly...different setups need different exhaust systems. Thus on a n/a engine it loses power with straight pipes as u saw above.

I hate when cars have no tone to them....reminds me of those loud fbodys....just loud...doesnt sound good at all.

I say you get some spintech side exhaust mufflers or maybe even dynomax mufflers and do it the right way. It will still be loud but it will sound MUCH better IMO. The spintechs are about $120 a piece(but worth it IMO) dynomax's are $60 at summit i believe. U could also just run some dynomax bullet mufflers are $30-40 a peice...still loud but tries to tone it down a little. If u want it louder after that, START MAKIN POWAAAAAAAAAAAAAAAAAAAAA

For the price those probably are i would just go with spintech. If u were set on that style of muffler save a ton of money and get the bullets. I have not heard those...so i cant help ya there.
