Looking to boost my car and will be needing an exhaust and downpipe. I'm thinking of having everything custom made since ill be on a $500 budget for exhaust and cant afford a premade kit. Anyways, what size exhaust piping do you recommend? 3" or 2.5"? Also, should I get stainless steel or aluminized steel? If anyone has any recommendations it would be appreciated. Trying to find somewhere that sells cheap stainless but not having much luck.

 

Bigger is better. SS is better.

That was surprisingly unscathing, is there something wrong? What has happened to your lovable hate?

Also, he's not wrong. Do some reading and come back with what you think will be the right answer. Showing you've put some effort in before hand will make you time here much smoother.

 

Also, unless you do all the work yourself and value your time at $0.24/hour, a kit like the mk turbo which includes the entire exhaust is going to be the cheapest way to go.

 

When I was looking online for tubing, I found that Columbia River Mandrel Bending had some of the more reasonable prices I found, after shipping (metal is heavy!).
