3" exhaust


Hatch92

Recommended Posts

a friend of mine just bought a '94 DX hatch. it has the b16 swap and a what i think is a t3/t4 turbo. he found a 3" catback from Thermal. would it be worth buying if he plans on running 18+ lbs of boost.....

 

anyone heard anything about Thermal exhaust.....good, bad, ok any comments are welcome

 

i can't realy help him i only have a 2.5" catback runnin about 10lbs of boost on the street on the street and about 15lbs at the track.

it would be worth putting a 3" pipe on it if hes gonna run upwards of 20 lbs sure. but payin huge money for a piece of pipe cause it was bent by a brand name? i think not.

i say, if theres an exhaust on it now, leave it, go to a shop and get a doqnpipe made that has a second exit with a block off plate, take off the block off plate and run an open downpipe, less backpressure
