iirc you'll lose some power by running w/out a cat, as you need a certain amount of backpressure
theres a huge argument ongoing in the honda worldiirc you'll lose some power by running w/out a cat, as you need a certain amount of backpressure
if your car is a turbo there is no debate on cat vs no cat,, no cat simply makes more power.theres a huge argument ongoing in the honda world
my view is...let the header do the scavenging and run catless
My 81 turbo car (8V) has no cat and I think that if it had cat the performance would be diminished. Not sure how this applies to 16V's as I thought all 16V cars had a cat due to the tougher emission standards that came about in the mid-80's in most countries where Saab's are/were sold.The untimate exhaust is an equation between cylander volume and expansion chamber size in exhaust behind header.
call Nat Wentworth at Erikson (sp) transmissions. He spend a good amount of time doing this and the result is an awesome sound with maximum power.
My short opinion... no cat
That's because they are fueled differently. You will get a small gain in power though.look at the power ratings on the turbos w/ and w/o cats.. good for 10bph from the factory w/o cat.... not that the n/a will make that much powa but its worth a shot if you got it for a song....
Did you cut that from a stock section and just clamp it? Does it perform better than a gutted cat?may not look pretty but sounds great and I swear I have more powaaarr...
