h pipe vs high flow cats
 

Hey guys, I have an 09 GT, I am debating whether or not to get a whole new catted h pipe or just get high flow cats. Give me some pros and cons

If your planning on upgrading to high-flow cats, your best option is replacing the stock catted mid section altogether.. Otherwise you'll end up having to cut your stock cats from the OEM mid pipe which just isn't worth destroying IMHO..

Therefore I would highly recommend looking into the Magnaflow high-flow catted mid H or X section or also look into Bassani, Kooks, Pypes and BBK as well.. Vendors such as Summit Racing, American Muscle, CJ Pony Parts and Stage 3 Motorsports all carry them in stock.

In the meantime, hope this addresses your questions and concerns regarding the pros and cons.. And btw: also welcome to TMS :nice:
