I've got 3" dual exhaust dumping at the axle, and i want to run it under the axle and out the rear passages on the bumper on my TA. However, I don't know if there are any dual/dual style tips that fit on 3" exhaust. I do not want big single tips.

 

I am also curious about this...

 

Corsa may have the tips you're looking for. Check em out. www.corsaperf.com

 

Corsa makes it and so does Slp and borla.

 

Is reducing from my 3" to the 2.5" hooker tips a bad idea for performance or sound?

 

If you're downsizing tips...there won't be any notable difference in hp or sound. If you're downsizing tubing from 3" to 2.5", then you're causing more restriction, thus decreasing hp... but so little it almost doesn't matter (to most).

 

So I would be better off just putting 2.5" tips on rather than reducing the 3" piping from the axle to 2.5" piping at and after the axle to accomodate the tips at the bumper?

How much of a horsepower and sound difference are we talking about?

 

I wouldn't even start to try giving you numbers, because the difference is so slight. Sound wise, it would probably take a trained ear to notice. What kind of exhaust are you using? Regardless of pipe size, i'm sure most people would be like, "that's badass" just because of the muffler. In terms of a stock set-up, I believe the piping was 2.75 from the axle foward, and reduced to 2.5 or even 2 into the muffler and out to the tips. So any increase from there is beneficial.

 

I currently have longtubes w/3" x-pipe and 3" true duals stopping at the axle.
