| Exhaust questions |
Subject: Exhaust questions by Big_John on 2005/11/2 21:30:34 I need a few opinions here. I have my '85 Corvette that I'll be using 1 3/4" primary Hooker 2151's with 3" collectors. Yea, I know 1 5/8 is better..what ever, I got a deal on these. Anyway, we'll be using the car for autocross only with no street driving, so no cats will be used. The rules I have to follow are simple, I have to run mufflers and the exhaust has to end behind the driver. I'll use some Dynomax race mufflers that are basically glass packs. From past experience, the cars are a little quieter with turndowns pointed at the pavement, so I'll use those too ending under the car just past the driver. I'm looking for mid range power and torque here. So..this brings me to my questions. After the collector, should I run 3" or 2 1/2" pipe to the muffler. Mufflers can be had in 3" BTW. Should I run a X-pipe? |
