5" Oval Exhaust
Finally getting the exhaust done. It's a 4" round down pipe to 5" oval to a 5" round inlet/4" round out muffler.
And as usual we are doing it all at www.twinsturbo.com.

We chose this size because of the massive turbo(83mm) and fitment.
It tucks in higher than 4" round and it obviously flows.
You should have seen how long it took me to find a muffler!
Oh and to make it even better the wastegate dumps to atmosphere! But I doubt I'll even here it.

LOL...nice, you really need to make a video of this when the exhaust is completed. One at idle and the other WOT pull.

I mean that's not THAT big... like a GT40. I think most people don't go 4 inches just because of the cost and clearance issues.

I can't imagine much of a performance gain going to a 5 inch from a 4 inch.

I`m doing it because I will run a smal housing hot side..

Only 0.91 on a GT42R, because I will run it at Time attack here in norway...
