Boost with no cat.

Re:Boost with no cat.
turbo doesn't like cat at all
I had a pipe on mine, but I went and purchased an obx racing cat... VERY NICE. It takes the smell out of your exhaust, but it's a straight through design with absolutly no restriction.

(Test info was pulled from the net, so I can only assume it is correct).
Stock NSX 242.1 cfm
Stock Type R 223.6 cfm
Stock Integra 218.3 cfm
Catco (metal core) 2.25" 223.8 cfm
Catco (metal core) 2.5" 271.9 cfm
Random Tech 2.25" 297.1 cfm
Catco (std. core) 2.25" 338.2 cfm
Catco (std. core) 2.5" 388.0 cfm
Car Sound 2.25" 342.7 cfm
Test Pipe 2.25" 407.1 cfm
cfm = flow capacity in cubic feet per minute
Unfortunately, the 2.5" Car Sound Cat and 2.5" test pipe was not measured. I've read that folks have had some problems with the Random Tech Cat. I sell the Car Sound Cat, frankly because Larry Widmer of Endyn runs it on his beast (3" version), he has had no problems with it over 3 years and has recommended to me.
