ok guys i heard some high flow cats set ups have a raspy noise i dont want that at all.

i have the gruppe s ypipe and looking to put high flow cats in the car.

so i just want your guys personal feedback. I would like a deeper noise without the rasp and a good product. any info would be appreciated

 

if you do not want raspiness stay away from RT cats and any test pipe (even if its resonated).

 

Get Crawfords.

 

Yep. Least rasp, best quality HF cats= Crawford.
