not sure what to go with my s.high flow cat. or just run the test pipe? im staying all motor. so only question is will my low end with the test pipe be a mild loss, or will the wot on top end justify it and bring a smile to my face non the less. i justified the race pipe with my n/a fc rx7 that i have. but not sure bout the s. any answers are help full. thanks john

The OEM cat is already a high flow unit. I bought my TP for $65 and have experienced great results. I would have done it sooner had I known. I have the AEM V2 intake and stock exhaust.

 

Berk high flow cat FTW. Flow rate is 87% of an equivalent length straight piece of pipe, whereas the stock cat is only 43%. When you look inside both of them you'll see why.

No test pipe stink and no baby fur seal killing

 

tp barely offers any gains over stock cat, so replacing a high flow cat with a high flow cat is a waste of money

 

hahahah this made me crack up.

 

I heard berk high flow cat works great.

 

The car used in the import tuner article was a civic, there are better gains in a s2000. I probably couldn't feel 1hp, but I can feel 5hp for sure. I love the sound. The only drawback is an occasional waft of exhaust with the top down.

 

test pipe is waaay cheaper, I got a 7whp gain on a back to back dyno. And I have no idea what this test pipe smell is mine smells just like stock. berk test pipe FTW

 

where can i get a berk, test pipe ,high flow cat. any links or sights.
