Does anyone on this forum have the GHL 3inch cat back exhaust? I'm so confused over which exhaust to purchase. I was looking more towards the corksport exhaust when I heard the GHL and basically fell in love with the sound.
Any suggestions...(alright)
 
It sounds great and very throaty. I'm having a problem with my CPE downpipe - GHL exhaust. I need to figure out the problem. Don't know if the exhaust has anything to do with it.
 
What kind of problems are you having? I was thinking of the same combination you have.

Running very rich with the high flow cat. After a while If I shoot a flame from WOT I'll get a hot metal smell. I think I'm running so rich which is the issue and it needs to be leaned out a bit.
