im about to make a choice do i make a exhuast for my car or buy one ?
i got all the tools to do it just got to buy the piping or just buy one

people tell me that a custom never sounds as good as a bought one but i think it got to do more with the choice of pipe and mufflers but thats me!

 

Sound differs between mufflers. Usually exhaust systems like Greddy Evo sound really nice and have little to no noise and carry a nice deep tone to them. This varies between cars of course. But if you notice Greddy and most aftermarket exhaust companies their mufflers are not excessively big but yet not so small. Usually those style exhausts have a deeper to subtle sound. If you don't believe me next time your on the road... when you hear a car that sounds like a go-kart look at the size of their muffler. When you hear a car thats sounds more mean or atleast has a nice flow deep tone/throttle sound look at the size of their muffler. I know this based on experience and the variety of mufflers/exhaust systems I've dealt with.

Its cheaper to just buy a aftermarket muffler then have the piping done at a shop. A cat-back with muffler install usually I pay around $100-$140. A aftermarket cat-back system from well known performance companies would vary on price but usually anywhere from $300-$600 and possibly even more.

This is my take on this. I've always prefered purchasing my muffler and then having a shop do the piping.

 

my world sport 2 from apexi came with some really sick piping and ya cost $400 but it was well worth it. Nice deep tone with out a raspy rice noise highly suggest it

 

I started replying but then I concentrated on Hater's sig. Those are some of the bitches form Sapphic Erotica, aren't they?

 

i'm plaining on doing my own

header into off road pipe then into a dyno max bullet muffler and a turn down pointing at the road..the whole system will stop right at my front seat

 

When I help people build their own system, to save money, we get pre-bent tubing from the auto parts store. That way if it gets bent up/damaged, you only have to replace a section of it, instead of the whole thing.

Sections also allow it to flex slightly, instead of stressing the system each time the car accelerates/decelerates.

I sometimes customize the rear sheet metal/bumper to tuck it under the car, so the cops don't see it as easily, as part of "urban camoflage". When cops see a performance exhaust, they watch you a little closer. Attention that you may not want.-Bob

 

Make sure it's mandrel bent...

 

anyone know any sites that give good info on building a exhaust

 

if you don't know how to weld your kinda screwed, i'd say just buy one if they make nice kits for your cars, it'll sound better and they may have done a little more R&D than you, but your car may not really need it, unless you know they company has tuned the exhaust

 

no no i know how to weld! i just wanted to look up some info on how to build a exhaust and to get the best flow
