Full Version: test pipe W/ custom exhaust
6G Celicas Forums > 6th Generation Celica > Engine/Transmission/Maintenance
last night i finally got my custom exhaust put on. I got 2 and a half, mandrel bent with a magnaflow muffler. IT sounds nice, very deep the testpipe also made it sound really good.
is that right? I'm hearing that 2.50 iz too big for our cars...
I'm not sure what a testpipe is. What is it and what does it do?
A testpipe eliminates the cat so you just run a straight through, then you have less restriction
I have had an arospeed muffler on my car for around two years now. I am looking to do the custom cat-back sometime soon. When you look at our stock exhausts it appears that we have two catylitic converters. Did you run the new pipes from the cat closest to the engine or the one furthest? Thanks for the info...
I have 2.5" on my Celi.
Got it cause when i went in they said they had 2.25", but when they got it up and cut, they didnt have the size. So they put 2.5" on instead.
