exhaust question

[adamforsythe]

Hello,
When I ordered my y-pipe, tail pipe, and center pipe I asked for a 2.5" pipes. When I started to test fit the pipes I notices that my tail-pipe was small. So I took a tape to it, it was 2" . So my question is should I return it and go through all of the crap. Or should I just by a reducers to bring my exhaust down to 2". I am thinking of taking it back. But I want to know what you guys think.
Thanks
Adam

Been a lot of exhaust threads lately, I'm sure this one will get crazy too.

From my understanding, and I'll be the first to admit there are a lot of variables that can affect this, the further back in an exhaust system you see a restriction, the less effect it has on performance. I believe the entire theory behind that is the heat shed through the system as the exhaust travels through the pipes. Still gains to be had, or cat back systems wouldn't be somewhat effective.

2" single has to be really restrictive though.

That said, 2" pipes look retarded. I think the minimum for LOOKS should be 2.5".

yeh 2.5" if full length would be reccommended

2" maybe if half length, maybe,..,

depends on engine though,

y pipe ? factory stock or aftermarket ?

emissions inspections there ? or none ?

if none then why not get stock dual pipes for pre-75 truck ?

some of the 350/400 trucks had duals, i forget which all applications,


good luck
