Wondering if anyone in the uk has replaced their cats with T1R, J racing pipes or anything similiar?

did you notice any performance benefits?

did it make a big difference in sound levels? the T1R claims its resonated so its not that noisy compared to some others. It is also half the price of the J racing one.

i have experienced noticeable performance benefits on removing a cat from my alfa 156 but it doesnt rev to 9.5K!I have a ricks manifold on order and will be purchasing the supersprint exhaust (still undecided whether silenced or straight thro centre section) and am worried about the sound levels if i swap the cat out.

 

Have a look at the numerous posts on this subject recently.

 

I have done a few searches most of the posts were from america. some guys were claiming the test pipes were the best mod ever and others were saying they werent worth the effort!

wanted to get the opinion of someone whos done the mod in the uk. if you know a good post could you possibly send me a link.

Cheers
