I have a little tick now that I have my magnaflow competition cat back. I also have a. Steeda tune and Cai wondering if a cat back can cause a spark knock or if its just a exhaust leak all bolts are tight as hell.....

 

most likely an exhaust leak, are maybe the clamps arent in the right place, that happened to me.

 

It's really starting to pi$$ me off lol so frustrated I just hope its not a spark knock.

 

From h pipe back its stock clamps and that's where the sound is coming from, and its only when I get on it and pushed the rpm's

 

you may need to adjust the clamps positions, if its something to do with the engine, steeda will back you up, since its there tune..

 

I'm gonna call magnaflow tomorrow and see if they can help. Thanks for the input brother.
