What style of exhaust would see a better power gain from, single or duals?

 

70mm single...

 

Single.

Just about every top Japan parts manufacturers have singles on their cars.

 

+1 for singles, test pipes also have shown to be the best bang for buck exhuast/mod wise on dynos around the forums.

 

Single. I'm thinking of selling my Tsudo dual soon and getting a single. I love the look of the dual, but I want the better performance the single offers, though it's not huge. But I don't want my AP2 bumper to look stupid with only a single.

 

I know theres a thread or 2 of some nicely done caps on ap2 bumpers, not sure how much it was or the shop that does it.

 

70mm duals Duals look much better and the gains from a single to a good dual are very minimal. Not even significant enough to mention

 

the power difference is indeed relatively minute, but paired with the additional weight savings (not to mention the increased ease of accessing the diff as a rear jack point), it made a single worth it to me.
