I've never heard a Y-pipe exhaust that sounds better than true duals. There's only so much you can do for sound and performance when you have all the exhaust gasses from both cylinder banks merging into one single pipe. I'll leave it at that.

Weight ~ expense ~ loss of ground clearance ~ 1 to 3 horsepower increase or less ~ and with the right cat-back the sound is just as good !

how much more do you think an x pipe would weigh compared to a y pipe?

1 to 3 HP gain???
Duals are worth 15RWHP over a catback system if done correctly.

I have BETTER clearance with my current duals than I had with my previous catback system.
No way a y-pipe into catback sounds as good as duals.

Hell yeah. Mrr23 dynoed a 20rwhp gain going to Bassani true duals over his catback, still using factory manifolds. The Bassani yielded even more power than the cutout http://www.stealthram.com/bassanidualexhaust.htm . The extra 20HP is about what a set of headers adds, and when combined with headers will provide even more power.

I'd like to see that dyno sheet. Was it an independent dyno test or one from Bassani ?
It appears to hang pretty low on the driver's side but if what you say is true it might be worth it .

Independent.

**M-Ten** · 11-11-2007, 12:58 PM

what's better.. a custom true dual or bassani?

**Mr. Luos** · 11-11-2007, 01:00 PM

Whichever is cheaper.

I believe the Bassani is over the axle, so it would be something you could install yourself with basic tools.

**M-Ten** · 11-11-2007, 01:02 PM

well the bassani costs like 900 doesnt' it? also its routed a different way right? if you have a custom you can run two pipes where the orginal Y pipe was and the bassani is different i think..

Vinci Performance did the install and dyno if I remember right. Contact Mrr23 here. Here's his performance & pics link http://www.stealthram.com/bassanidualexhaust.htm . Here's his webpage http://www.stealthram.com/2000pontiacformula.html and http://www.stealthram.com/1999pontiacformula.html . I installed my own, took 2 hours with a buddy and a case of beer.

$779 delivered is what I paid. I couldn't find an exhaust shop to run true duals over axle. Everyone wanted to go under or dump. Considering the gains over a catback I felt the extra cash was well worth it, and still feel very strongly that this was my best mod so far.

Like I said before, for someone considering a catback and headers, the bassani is comparable in cost and power even using the stock manifolds. It allows headers to be added for even more gains later.

**M-Ten** · 11-11-2007, 07:39 PM

is going over the axle better than going under? Also does the bassani come with mufflers and everything or is it just the x pipe?

I think so. Certainly appears more stock. Bassani includes all hangers, muffler, pipes, x-pipe, a torque bump stop, and even the anti-sieze. It bolts right to the cats on 00-02 F-bodies. All you need is a sawsall to remove the old pipes, a rubber mallet, and a socket set.

**99'CajunFirehawk157** · 11-11-2007, 07:52 PM

Where did you get the bassani for $799 dlvd? I like everything about it except the way the rh tail pipe swings back aound behind the muffler...anyone have a sound clip? What about for us 1999 owners?

**M-Ten** · 11-11-2007, 08:06 PM

yeah a sound clip would be nice.. is it possible to remove the cats w/ the bassani? also what is anti-sieze?

**99'CajunFirehawk157** · 11-11-2007, 08:19 PM

also what is anti-sieze?

A compound (paste) that you put on bolts that you dont want to freeze up...

**M-Ten** · 11-11-2007, 08:23 PM

oh ok thanks

Vinci Performance sells it for $779+ delivery. I'll PM you where I got it (non-sponsor). Mrr23 has it on a 99 model. It requires a little pipework. PM him...

The anti-sieze is for the slip fit connections. Bassani installs aft-cat, so removal would require a pipe fabbed up to connect it to headers or manifolds without cats.

Here's a Bassani clip I made right after install on stock cam, cats & manifolds: http://s217.photobucket.com/albums/c...nt=Bassani.flv
I've since added headers and high flow cats, and it is a bit louder.

Mrr23 has 2 clips, for a 99 and for a 00:
