Like I have time to make up shit like this
EVO 8/9 with a HK$ canister JDM foo-foo muffler. Inside all the 3" piping and phat 5" tips they always put a restrictor. Always.
That is looking in the HK$ phat 5" tip at a 3" ID muffler with a 2.5" restriction. Dude sells his entire setup except for the exhaust system to his buddy. Put it all on his buddies car and the car is down on power. What is different? Stupid JDM wannabe exhaust. Drop the restrictive JDM stuff and run the car mufflerless and there is the power.

Happy owner of an RRE stealth and the last evo, 2006 se
I have run stock exhausts on 2 EVOs, an HKS carbon Ti on 1 EVO, and the RRE stealth on 2 EVOs. The Stealth is the best for many reasons. One of them is dyno sheets, which actually is the last reason I want it...but it is a nice perk.
If you search around, you will find no less than 50 threads dealing with this issue in relation to various aftermarket exhausts.
ohhh mike.. I feel sorry for the sparking JDM muffer along with the JDM Stickers Dyno proven parts is the best to get :)
what about Ti exhausts any cons besides the loud and police attention magnet? All JDM exhaust have 2.5 restrictions?
