Hey everyone,

I'm installing a 3" engine back exhaust system onto my 97 GST FWD. I've got a 3" Cat Back system and i've got 3" Downpipe. I can't seem to find a 3" CAT or Test Pipe.

I've only been able to find 2.5" sizes on both. This seems very dumb to me. Anyone else run into this issue?

I had one back in the day 10 years ago.

if you can't find one... just go to any autoparts store or an exhaust shop and buy a measured section of 3" pipe and start welding (or clamping if you prefer)... it's the DSM way

I made a lot of my DSM parts when I ran my 93 GSX... and a lot of guys here make their own parts too.

that was the next step, i was trying to avoid that but true...it is the DSM way isn't it haha

How long is your DP? Mine was long enough and just replaced the cat..

Havn't had a free evening to jack up the car yet, college is almost over and then i'm going to tear apart the car and re-do alot of it.....re-do it right this time.
