Hey those who have this.. i just installed it and was wondering did you guys feel a major difference...? i feel some more pull but its not really impressing me... The thing is i still got the cat inbetween the catbak and downpipe... so if i get a testpipe will i feel even more pull??

 

I had the Invidia down pipe for a week before I installed the test pipe. I felt a significant difference with the downpipe alone. After the test pipe, the entire exhaust flows a lot more freely. You'll feel the difference in performance after the test pipe. It's not neck-snapping pull, but definitely less restrictive.

 

I agree. Justa DP you will feel a bit but with a test pipe it will feel much better. get an UR test pipe for $75 and your good to go

 

how does the UR test pipe not cause a cel?

 

It's hard to explain, but it has a bung welded on to it to move the 02 sensor away from the exhaust stream, it works really well. Ive had mine on for at least 15K miles or more and no CEL. And the best thing is it just bolts in no modifying anything.

 

so test pipe is still cat delete, so it's loud?

 

i think it depends what exhaust u have!!!

and test pipe is cat delete!!!

 

Agreed, I have had it for a while and I dont think its that much louder.

 

I have the Invidia dp and test pipe hooked up to the Greddy Ti. I definately feel a difference up top. If you still have ur cat on I dont think the gain would be much, but should still flow much better than a stock dp.
