Hey all,

I've been looking online at the differences between running high flow cat with downpipe vs just catless and was wondering regarding our specific car is there a huge noticeable difference in power gain in going with one or the other?

What are the benefits of running one vs the other?
Catless and straight pipe , is no restrictions. Also IC aftermarket IC piping and 5 more PSI of boost and you will get 250hp even little more.

For race applications, sure. For city driving straight pipes create a TON of drone at mid-RPM's. Plus the smell. High flow cat, resonator, and muffler delete is the way to go
