Hey Guyz, 2 quick questions: 1.Which exhaust setup would be more beneficial? The true duals with no cats, and Dynomax turbo mufflers, or the RP catback system sold by Rotary Performance for $395? 2. How much do the pulley kits improve your performance and horsepower. BTW besides the reliability mods, all I have is intake. THANX!!

 

For a street driven N/A, your typical 2.5" race pipe into a single exhaust is more than adequate. Any of the typical systems out there will offer power gains, provided the auxilary ports are kept in working order.

Pullies belong on race motors. Do not expect any hp out of them on a street engine (and that's 1/5 the price of a NOS wet kit!)

 

THE VEHICLE IS AN 88 N/A

 

My comment was written for an S4 NA just like yours.

 

SCATHCART, just dawned on me, Ive heard you talk about your car on many occasions, but never actually seen it. Direct me to some pics?
