Has anybody done this? I bought the cat back off a buddies GT500 and I'm gonna put it on my car.

Nope, but watching to see how it turns out

Just hurry up and do it already

Know for a fact the the GT rear diffuser runs small around the exhaust exits. GT500 runs 5in tips and the Gt500 diffuser is 2in wider in that area. So he's giving me his diffuser and we are gonna swap. Happing in the next week or so.

I think it will fit in general, but the tips won't align as well.

If you look at your tips from the side, they come straight out of the muffler. If you do the same on the GT500 one, the tips have a slight angle to them and sit a bit lower overall than the muffler. So they may hang a bit lower than where the hole is in the valance.

My active exhaust tips lower down and dont come straight out

Us swapping valances should remedy all this, I'd imagine.

Alright, Folks... The conversion is complete.

I don't, unfortunately. Just warm idles. I forgot to mention this is coupled with the Steeda x pipe.

no issues, it sounds really good though. What are your impressions of the change?

 

[theslerg]

Definitely have more volume when under acceleration! Down-shifts sound great will subtle burbles. These are my impressions from inside the car, tho.

Inside is great when cruising but when you open it up, it comes to life! I'm very happy with it!

Good stuff, glad it worked out and you like it.

 

[Soonertim4]

[theslerg]
