I know there are clearance issues with header/y pipe with a t5. So what combos are out there that is known to fit around the slave cylinder and such on a t5 car. Thanks

 

Not a problem with shorty's

 

So any shorty header and y pipe will clear the slave cylinder

 

I've had Edelbrock and SLP in my car. Both fit fine. The SLPs fit a T-56 as well.

 

AFAIK they all fit and clear the slave.

 

dons fit mine like a glove.

 

HEDMAN headers and the matching Y-pipe did good for me and my T5.

 

Short Hedman headers.

 

If you can cut and weld, you can make long tubes fit. I've got Hooker 2210s on my IROC with a Tremec TKO600 trans. They fit pretty decent. My dad has Hedman long tubes on his car, the collector hit the slave mount, but he cut the collector off, slid it forward, angled it down slightly and all is well.

I will say however, that if you're making 450hp or less, just go with the Dyno Don shorties. Way easier, way less work and better ground clearance.
