well, im planing to get some Skunk 2 stage 1 cams and im wondering if an itr exhaust would work well with that set up. I currently have a GSR w/ 2.5 piping with a trust exhaust but i want to make my car quiet and sleeper. Will i lose power if i switch to itr exhaust? is it too restrictive? My mods are CAI (soon to be ICEBOX), dc 4-2-1 headers, Carsound cat, cam gears, vtec controller, and 2.5 trust exhaust.
I wanted to post here because i want the opinions of itr owners.

 

I would keep the 2.5 if you are doing cams. Dont waste the money for an ITR exhaust

 

I recommend a comptech axleback. Keep all the piping

 

SMSP!!

 

i'd say get the itr exhaust, it will restrict you, but it's ok for a street setup. get a header (2.5")and a custom a cat that will bolt onto the itr catback. once you hit the track, run it open header
