10-15hp gone too.....

 

YOUR EXHAUST WILL DO ABSOLUTELY NOTHING FOR YOU WITH YOUR STOCK CAT ON.

 

no way 10 or 15hp. maybe cat deletes (down pipe) for boosted cars

but no way 10-15hp for the s even with corresponding bolt ons. Maybe around 5hp max

 

yes maybe 5 i balieve you..

 

BERKs hiflow cat

 

like i said 15-20hp gone too......

 

Keep the Tp, Replace the Invidia N1

 

It's quite possible u had an exhaust leak...I've heard the Invidia N1 w/ TP on several cars and neither were raspy...Still loud but not raspy.

The only Invidia exhaust I've heard with a TP that was raspy was the Q300(v4) single.

 

Get a Berk HFC.
Avoid the Asura HFC at all costs, very very poor customer service at Asura.
