Ive got a GT h-pipe mated to my oem cats with a complete GT dual system.

Is anyone running either the oem 1 legger, or is anyone running a full aftermarket system from headers back?

 

I have mac shortys, cats still in place, magnaflow X-pipe, magnaflow mufflers under the car, tru-dual system, many, many, many ways to go on this one

 

I have a GT takeoff on mine. I cut the y-pipe right after the cats and welded the GTs h-pipe in its place, then regular GT hardware the rest of the way.

Im just curious if anyone thats FI is still running the 1 legger.

 

I've been single all along... Just recently went to a custom off-road y-pipe... but still a single...

hey... so does that make me the fastest single exhaust??? LOL

 

Yep, fastest non-shop owned single. PH is running a single on the V6 car as well.

I have dual American Thunders on my turbo setup, sound clips of them on my web site.

 

And soon to be the fastest on SNOW TIRES!!! Now to find an open track so I can get a timeslip!!! LOL!

 

You need professional help. LOL.
