The difference
between a 2 ½” and 3” for the street is minimal as far as horsepower. I looked
at Pypes last year at Carlise was not impressed. I bought my exhaust from Jeg’s.
I will send pics if you want. Part number 555-30551 $175. or 555-30555 $195. for
3” and H-pipe kit 555-30651 or 555-30652 add $30 -----Original
Message----- I'm in the market for an exhaust system,I Have a mostly stock
454ci .60 over, mild cam with a street avenger 770 , stock open
chamber oval heads ,super comp headers and would like to know if I should
go with a 2.5"inch or 3" inch pipe. The anyone has had any
experiance with Pypes 3"inch crossover system with cut outs. looks like a
nice system, but more expensive than Flowmasters. Jimmy C. |
