So ive got an 87 GLHS that i want to upgrade the exhaust on. I was thinking on going with the full 3 inch system from turbos unleashed with the test pipe they sell for the cat so it would be 3 inch from dp all the way back but from what i read i would need to upgrade my 2.25 dp to a 2.5 or 3.
Or i could keep stock dp and add 3" all the way back from there. The exhaust that is on it now has a few rust holes in it so it sounds bad, so i need to upgrade. Any suggestions on what i should do? Oh yeah the upgrades my GLHS has are stage 2 computer and a K & N air filter. Thanks
