Contour Enthusiasts Group Archives Forums Modifications Forced Induction Bosal cat-back looks to be a FI winner...

Judging by the amount of "extra" exhaust produced by force induced Contours, I think this new Bosal cat-back system is best suited for it. All mandrel bent pipes, 2.5" before the split, 2.25" after the split, 304 S/S, chrome plated, and straight-through mufflers/resonator. This is exactly the cat-back I was going to have custom made for me, and now it comes in a bolt-on package (not slip fit/crimp).

And, considering the reputation they have for VW, BMW, Honda, etc. I feel even more comfortable getting it. Not to mention we have a rep from the company roaming around these boards (Bandit).

For those of you that just happen to be running stock exhaust with the Vortech, I would jump on the group buy. $500 shipped directly from the manufacturer isn't bad. One has my name on it, for sure.

Of course, this is just my honest opinion.

Brullen has the same thing. I think Brullen is better because you can choose different options like resonator/tips/mufflers.

I definitely disagree with you!

It's much too small for forced induction or 3L engines.

2.5" O.D. single piping is just not large enough.

Now this would make a decent setup for any NA 2.5L not going true duals.

Provided of course all the mufflers are straight through??? (couldn't find that info)

I agree with your disagreement. 3" for FI, no less....

I would say 2.5" is large enough for any N/A setup seen here, be it 2.5 or 3.0L. But like you said, I'd prolly go 3" on a forced induction setup.

So, would you say 3.5" for a TC3L?
