Hello everyone,

I just had the new Bassani True duals installed on my 2001 Z28 Camaro. They sound great. Very impressive dual exhaust sound. I was worried about the exhaust being too loud since I have Hooker Long Tubed Headers with no cats. It sounds is perfect. It's not quite as loud as my burned out Hooker Catback exhaust but it has a much better sound.

The car was dynoed but there was several other things done since my last dyno. By having my Patriot heads redone (reported, port matched exhaust & intake, 2.055 & 1.600 valves), Accufab throttle body, under drive pulleys and of course the Bassani True Duals. On a mustang dyno I went from 360 rwhp to 406 rwhp. I am hoping for improved track times. I was at 12.34 sec @ 110 mph. I am hoping for 11.9 sec at about 114 mph. I guess I'll have to wait until April when the track opens to find out.

Hey those are awesome results! Almost 50rwhp gain. 406rwhp on a Ford dyno in an A4.

I thought the Bassani was made to mate up to the stock manifolds. Is that true? If so, did you have to cut up the exhaust to get it to match your headers?

Yes, it is set up for stock. I bought some Flowmaster 3 to 2 1/2 reducers. They slid right on the ends of the headers. We cut off the compression fittings, welded the pipe to reducer on the passenger side and had to weld a 7 inch peice of 2 1/2 from the pipe to the reducer on the driver's side. Worked like a charm. No clearance issues. Sounds great.

Regards,

Al

 

Gonna need some pictures man.

 

In the morning I'll crawl under and get a few pics. I'll try and post them tomarrow.

Did you get the stainless or aluminized version? If aluminzed what is your opinion of the quality?

Are you running an after-market Torque Arm or stock!

Reason for the question is I have a Spohn frame mounted torque arm with drive shaft loop and don't want to order a Bassini if it won't fit with the Spohn TQ.

I also have a Moser rear end and thought there might be fitment issues since the axle tubes are bigger than stock which changes the location of the sway bars somewhat. I see you have a Moser too, so apparently there aren't any fitment issues with the Moser or the difference in location of the rear sway bar. I also have a larger BMR sway whose location is changed because of the larger axle tubes on the Moser.

I emailed Vinci but never got a reply with a good answer. Their answer was we don't know.

 

I have the stock torque arm. I'm not sure about the frame-type mounted torque arm but the aftermarket TA that still mounts to your transmission will work fine. I did have to switch from the SLP Driveshaft Loop to the BMR Driveshaft Loop and it fits perfect. The X-pipe does cross directly above that location. You might give Vince Hi Performance a call. They were able to tell me about my drive shaft loop before bought it.

I do have the Moser 12 bolt rear-end and the pipes clear everything with no issues.

For you’re other question, yes it is aluminized. The quality seems pretty good (no rattles) but the gauge (thickness) of the pipe wall could be a little thicker.

The part I like best is the increase in the total volume (area) of the pipe goes from 7.07 in^2 for a 3 inch I-pipe to 9.8125 in^2 volume (area) for the two 2.5 inch duals. That is a 38.89% increase in volume (area). Plus the sound is much better (not louder) than the Hooker Exhaust. It has approximately the same volume (not tone) as the Hooker Catback.

Good luck,

Al

P.S. I just looked at pictures of your torque arm and compared them to the pictures of the BMR DS Loop and I have my doubts about the compatibility of this exhaust and your torque arm.

 

If your cars lowered, dont even think about buying it. I wish I had never bought it, ive had so many issues im considering ripping it off and selling it. I have the SS version so it was a grand.

 

and what are your issues? i remember you having a post on the old ls1.com before it went down. i remember one of the things was you were using the supplied washers and bolts that were to be used to lower the tunnel brace for trying to mount the muffler. the bassani uses all factory hanger locations. you use the existing mounting brackets.

 

it's made to hook to the factory 00-02 cats. as seen in this pic from under my 00 formula.



you can modify it to hook to different style headers. you just got to figure it out. here's some pics of when i hooked it to the bassani headers on the wife's 99 formula.

The bolt thing was a nuisance but not a big deal.

1. Car is lowered, the overaxle part hits the axle on every bump, it has about 1 inch of clearance. I even put 3/4 inch polyurethane seats on top of my springs to raise it up and it still hits. It was wearing a hole right through the pipe, I had to wrap my axle with a silicon coupler to keep it from putting a hole in the pipe. I plan on cutting this entire section out and going under the axle this spring.

2. Once installed the driver side part off the header that has the polyurethane bumpstop was about 3-4 inches from the bottom of the car, so it literally was half an inch off the ground, I had to have a shop bend the pipe a good bit so it would be where its supposed to be.

3. It was smack up against my lower panhard bar and rubbed it every time i hit a bump, theres actually a crescent section taken right out of the panhard bar from it rubbing until I cut the tubing off the xpipe shorter so the rear section could slide forward another half inch to an inch.

4. After moving it forward somewhat so it wouldnt rub the panhard bar, then the other pipe sat right on top of the upper panhard bar so I bought the relocation kit/bar that gives more room.

I dont know if some drunk guy welded mine together or what, I looked at your pics on your site before I ever bought it and yours looks to fit perfect compared to mine. Your front driver section looks level off the xpipe, mine angled downward quite a bit. Im sure if I had a stock unlowered car I probably would have had no problems with the axle, that is my primary grief and anger about this system, and its not like I have an eibach sportline, its just a prokit.

 

sounds like the lowering created most of the issues. when i first put mine on the 00 formula, it hit the upper panhard brace as well. but, that was it. the front driver's section sounds weird. do you have pics of it on your car so i can see them and forward to bassani?

 

I knew you were gonna ask, i just went to best buy and bought a digi cam so I can take pics tomorrow. Ill take pics and post them.

 

Left is front of car, xpipe is just off to the right, that pipe is driver side section between xpipe and header.

You see how much of an angle the xpipe comes down, i had to bend it so it isnt practically dragging on the ground. The night I put it on, i drove through a completely level stone parking lot and i was hitting stones.



Driver side header to xpipe

Notice how it goes down a good bit, its primarily the angle coming off the xpipe thats the problem but this doesnt help. The bump stop there is about 3/4 of an inch from the bottom of the car, before i bent the pipe up somewhat it was about 3+ inches

 

Damn that thiing hangs loooooow!

 

I know man, before i bent it.........it was like literally on the ground, and actually even with it bent you can see its still low. I put a piece of metal across my tunnel brace mounts and jacked the exhaust up a little so its even a little higher then it was.

I hit it on everything, anything over 1.5-2 inches it hits.

 

heres another pic from the passenger side



mrr23, is yours like this? from your pics it looks completely level with the rest of the system

 

here's mine. my car is stock height. that tape measure almost 4.5" now subtract how much you lowered your car and that's what you should have.

 

So I should have had 3 inches, but before i bent it i had about 1 inch. I now have about 2-2.5 inches after bending it.
