Re: Exhaust removal questions (worth saving?)
Russ, if you don't mind what kind of #s did you get stock? If I remember when I did mine Stock it did 324rwhp.

Re: Exhaust removal questions (worth saving?)
Around 296-299 RWHP (five runs, two different dynos).
I have Marc's chip, wired open secondaries, new coils & injectors, (everything else stock, 67,000 miles). I went to the dyno to get pre-header baseline numbers. I was expecting something closer to 330 or so. Yesterday I sent my chip to Marc for recalibration (more fuel for the headers). We'll go back to the dyno after that and hopefully I'll be around 345-350. If not then we've ruled out the clogged exhaust as my main issue and I'll need to look at other possible causes. At first I was disappointed with the low numbers (and that's why I went to another dyno a week later, for confirmation). Then I realized there is a bigger jump to be gained, so it should feel pretty great after fixes and current underway upgrades.

Re: Exhaust removal questions (worth saving?)
If you decide to junk the exhaust I'd be interested in one of the mufflers,well actually just the exhaust tips.

Re: Exhaust removal questions (worth saving?)
That's not bad numbers Russ, After I did Marc's chip and just cat-back flowmasters I did 339rwhp-346tq... the next step was to the 510 package. I ended at around 490 at the FW but I still run cats and duel mass FW.

I know this is wishful thinking, but I REALLY hope I'm satisfied/content with the car after headers. There's no doubt the 510 package is fantastic, but that would mean my cheap "$10K Corvette" investment (the initial price I paid for the car) would grow to $25-30K. I doubt I could hide that expense from my wife. She's already commenting on my checking account balance's rapid decline. Therefore, please don't ever give me a ride in your car. :-) |
