Exhaust

[foxhound888]

i want to get the hks high power exhaust but don't know if i should get the 65mm or the 85mm i just have a '90 ka24e and want to buy stuff that can kinda be universal if i wan't to do a swap but the universal part is not as important as getting the perferred size for the engine?

i would get the 85mm for more power. i dont see any reason to get the 65mm unless you had a stock sr20de lowport.

would you guys recommend the hks high power exhaust or not? also does the test pipe offer much more power than the catco high flow cat?

why not get the 85mm high power? Personally I like my 5zigen proracer though. Gives more power than the HKS but also much more expensive. The test pipe doesn't offer power over the catco. Stick with the catco unless you've got a very good reason to go test pipe.

ok thanks for the replys, anyone else have any comments about my choice of exhaust? also is the catco significantly better than the stock cat?
