What horse power gain would you get from a 3" exhaust on a stock GT4?
I am using HKS Super Silent Exhaust and 3" Custom Stainless Steel from my Blitz Downpipe.

Actually you dont wait to get big gains from the Exhuast Upgrade but it can help you later on with your upgrades and when that "holy" time it comes for you to raise the boost smile.gifsmile.gif
i have 2.5" custom from my 3"dp all the way back(over axle ). I actually wanted the 3" but the exhaust guy came back to me during the installation and said there is clearance issues with 3"..so I went with the 2.5".

i just wish i did my rear over axle area different.


Can you elaborate ? I'm going to get mine done soon, also over axle.


sure, fastbird posted a ton of pics, youll see in the rear how he has his routed... i wish i went that way. i went the way the stock runs.. it clears b/c of the smaller diameter, but 3" clunks..


aww man...3" clunks? i was hoping it wouldnt. why do people do it over axle besides clearance issues?


for me right now yes. just depends on where you run it or how tight you can get the bends were u want them. look at fastbirds exhaust.. i have some exhaust shots in my profile you can view aswell. i ran mine this way just b/c its how i wanted it. jeff ran his under and doesnt have a problem, looks great to but i wanted mine differently, and my muffler would look soo terrible if i ran it like his.
It is unnecessary to go over the axel for clearance issues. All it does is give a less direct exhaust flow which will slighly inhibit performance - not to mention have more of a chance of rubbing on bumps.

I had to end up going with 2.5 due to the axle clearence...they also noted that even though they could bend the 3 inch right up around the axle, there is a very good chance that i will hear it rub on every bump. Also they would hoook up my down pipe because it would be illegal or some garbage so ill have to do that on my own time. Plus i had to keep the converter cuz they wouldnt remove that either.. Ya hard to find places in WI to bend some rules.. However the guy was really nice and i have no doubt that he'll do a good job. Im not too mad since i dont plan on turning up the boost anytime soon. Plus 2.5" costed me 80 bucks less.. Have any of you had problems with clearance for the 3 inch set up??
