Q Header or B&B first???
Mine is a 90 ZR-1 with 2-1/2" Borla catback(?) - the resonator looks stock, how-some-ever
 . Which would give the bigger 'bang for the buck', assuming the top end was ported and you could do only one (headers vs. 3" B&B) at a time? I would think headers. What sez U experts? P.

Do the headers first; pipes have to fit them.

Re: Q Header or B&B first???
Headers and a ported top end are the way to go. Then figure out an exhaust.

Re: Q Header or B&B first???
Just FYI, I had a ported top end on a stock exhaust. Changing the exhaust yielded ~25whp gain. Then adding headers added another 20whp.
The stock '90 system is pretty bad, especially the resonator. But if you have a Borla system, even if it's not your fave, it is likely better than the stock system. So I'd say headers. But if it's a stock exhaust, I'd say exhaust.

Digressing/hijacking my own threads a bit...Sound wise? I have the Borla, but on a scale of 1-10, I'd give it "6" I've heard the Corsa on the LT5s from the outside...definitely a sound of it's own - not what I'm looking for, but diversity is a good thing. I luv the B&B sound with the LT5. I'd like to hear the Flowmaster system behind the LT5 to compare with the B&B. Thank you (and everyone) for your thoughts. It would be very difficult to get up to speed on these Zs w/o the wealth of expertise residing on the Registry. P. |
