Hello,

Would anyone know if switching to a single exit exhaust from a dual would actually make a difference in horsepower and performance? I currently have a motordyne catback full exhaust with headers and test pipes and was thinking about switching to a single exit. I have read many different posts and have gotten several different answers. Would like to know what you guys think.

Thanks

 

Top end power will go up. Number on your dyno sheet will be higher. Sound will drastically change going from Motordyne to Tomei.

Given two cars with all same modifications but these two different exhausts, I would say driver would make a bigger difference than a single exit vs a dual exit (with the exception being boosted performance).

 

Stick with Motordyne. Not worth the switch. A tune is really needed to benefit from any bolt ons.
