F22trainer Posted May 18, 2006 Share Posted May 18, 2006 Thinking about getting headers and new exhaust - to help run cooler, as well as better sound. Like you Ken, I got 120+K on the motor. I think the cats are falling apart already, but the rest of the exhaust system is in good shape - maybe just headers???Your comments, please...

Quiktrip Posted May 18, 2006 Share Posted May 18, 2006 I think that some of the early C4 guys are going with long tubes and true duals back to x-pipe and muffs. A little more money, but they swear by the sound and added power. You would need the two high flow cats like the LT-1s use.Now, aren't you sorry that you asked?

F22trainer Posted May 19, 2006 Author Share Posted May 19, 2006 If the cats ain't flowin thats gonna back everything up. TURE THAT...had that hppen with my Nissan and Dodge PU. Actually shot a piece of the cat out the exhaust on the Nissan!PAH-TOOOOOEY!!!! Saw this smoking chunk o' stuff bouce down the road when I gunned it, because it was really lugging and I thought might help to mash the pedal to the floor Link to comment Share on other sites More sharing options...
92ZR1Wannabe Posted May 19, 2006 Share Posted May 19, 2006 Hooker super comps , corsa catback , O and no cats at all. I think it sounded nice on the dyno O and Quicktrip was right , alot of L98'rs switch from the 2-1-2 system to the true duel system. Link to comment Share on other sites More sharing options...

Header gaskets look pretty funky imho. Link to comment Share on other sites More sharing options...
F22trainer Posted May 19, 2006 Author Share Posted May 19, 2006 Thanx for the feedback - more is welcome...I got pencil'd in with Merle for some headers and a Corsa exhaust - and it will be a true dual set-up. Can't wait to hear that!!! He says I should get another 30-35 HP and should run/breathe better. Yea it's just a stock L-98 - won't do anything else to it until it gives out - then I'll do her up with a custom built job...unless I trade her in on a newer model, of course!Hey new thread maybe - how hard was it to part with your fiirst 'vette???

Header gaskets look pretty funky imho. My ZZ4 engine also has the D shaped exhaust port. GM did testing with both regular headers and D port shaped headers and found no difference in power. You can use regular shaped headers on a D port head, as long as the bolt pattern is the same. LT1 - LT4 heads may have a different bolt pattern, I don't know.

He says I should get another 30-35 HP and should run/breathe better.I'd bet real $$ an L-98 given a colon blow, will not get you 30 rwhp!!Intake mods and a chip burning guru along with the exhaust may be needed for 15-20!!These cars don't 'relearn' like the new ones to 'get you by'!!I'm in the same boat now Bro, so don't kill the messenger!!Ken Link to comment Share on other sites More sharing options...
F22trainer Posted May 19, 2006 Author Share Posted May 19, 2006 Merle' bettin' 30 -35!!!Right on the money Ken...$$$, being thte operative word!I'll be real interested to see what kind of gain I get...I mostly just wanted to help it breathe better, run cooler and any HP gains is a bonus...plus I would enjoy a little meaner sound but nothing that makes it a hedache on road trips.
