Exhaust

Hey guys i drive a s13 with a slant top sr20det with management. I would like to removed my middle silencer box but is it safe iv been told i could burn valve's, oh and i have 63mm exhaust.
Thanks

best exhaust is no exhaust!!!!!
the turbo gives the needed back presure so no burnt valves .

ps fit 76mm with one box you will be smiling

Agreed, fit a 76mm. When I had the car I had that pipe on with only the backbox.......it f*#kin LOUD! Car alarms go off when you drive past it!

It wont do any damage to the exhaust, but you wont benefit in power.

Hi guys, my CA is stock std and I want to upgrade my exhaust system to 76mm but getting alot of conflicting views from exhaust fitters, such as the T25 turbo lifespan will be reduced due to the diameter of the pipe "76" ,,, others claim 63mm is the best option as the turbo exhaust housing maybe example 45/50 mm so 76 is way too big. I would appreciate some input from you guys ... If any of you have fitted a bigger exhaust system to your std CA, what was the advantages and disadvantages ... Thx guys in advance for any and all your advisee.

Thanks guys so i should go 76mm and would that give me a slite performance upgrade or alot.

advantage = horsepower increase
disvantage = fuel consumption increase

my ca runs std turbo after the 76 exhaust it was verry nice power gain 76 is the best way to go .

if you get smaler you will kick your self as you will be paying twice

Slight performance gain especially when you remap the ecu, also better spooling....
