Good to know. My header and header-back are loud enough as it is. If it won't be louder, maybe I'll keep them on and go with a custom tune.

4. That's something you need to discuss with your chosen tuner; there are a lot of different philosophies.

2. I know I won't get much over the CARB tune with a stock header (see #3, below)
3. I already have a full exhaust with just one high-flow cat in the header. P&L EL catted header, P&L OP, P&L catless FP, P&L catback. I'm trying to gauge whether I should go back to stock. If baseline is 160 whp and CARB is 240 hp, what should I expect out of a 93oct tune with my aftermarket exhaust parts? If it's only 10 or 15 hp more, I'd rather go back to stock and CARB to quiet it down. If we are talking 20+ hp then the drive and noise could be worth it.
