Ok so i took out my crappy fast intention high flow cats. i was not impressed with them at all. i was told to use hi temp silicone to seal. but still got a cell, then used non foulers didn't help. i ordered some berk gaskets. well i installed the gaskets after spending an hour cleaning the silicone. the flanges on the high flows were curved and not flat. but of course i discovered this after already installing the gaskets. so i sold the cats and got the test pipes. still got a cel. ordered new o2 sensors thinking i damaged one. but the code i had was different this time. after talking to tony at motordyne, i had the codes for the fix they made. but he wanted me to try the brillo pad first, to see if it worked. so far im over 300 miles no cel. i will keep an update on how long this last or if i finally do get a cell. but im happy to have my cel off. now to get rid of the damn low tire light.

 

any gains?? im thinking of purchasing a set soon... i had strup test pipes and it seemed to help alot on my 03 but how good does the hr react?? let me knoo

 

sound clip?

 

They make proven gains just like on the 03. With my agency power its a bit raspy in the lower rpms but it stops at about 4500rpm. I need to sound clip my exhaust with the test pipes. But its loud as hell.

 

raspy to 4500? that's lots of rasp

 

my experience with testpipes in not good.. they sound terrible.. broke two sets of them infact..
went back to stock.. good luck with the CEL man.. glad I have an 03.. NO CEL

 

lol if your going slow to the rpm is lots if you go fast its not so bad. i have a custom ypipe im working on. i have to order 2 8" vibrant resonators to mount in my shortend, ultimate racing ypipe. it should take care of the rasp, still sound good, and I am at almost 400 miles still no cel. so im happy.

 

bump for vids!

 

i have them in my car combined with an hks exhaust and stillen headers. they sound amazing. It only rasps when you go full throttle
