Question for you about exhaust tip diameter

[Venom 1000TT]

This is the best picture I can come up with. They are 4" and look way nastier than the 3". They fit perfect.. no mods.

I like the 4" CORSA best of the 3 types on our rear exhaust Vipers....about a quarter of an inch of room on each side...bottom touches, but NO PROBLEM with heat as tips COOL, even in the summer heat here in Indy. I have helped other members install the CORSA cat-back on a 98 GTS, 2000 GTS, 2000 RT/10, and a 2001 GTS...same general fit in rear with only minor differences.

Tip : use duct tape to thoroughly cover the narrow fascia bar at the bottom of the exhaust exit opening BEFORE YOU TAKE OLD EXHAUST OFF TO AVOID SCRATCHING CHROME TIPS ON EITHER THE STOCK MUFFLER, OR THE EVEN BIGGER TIPS ON AN AFTERMARKET SYSTEM.

Those 4 inchers look pretty cool. The ones I was looking at were 10 inches long, so they'd have to have the 4" diameter running right through the tail panel. That was my concern.

What diameter exhaust tips do you have on your car, and do they fit through the opening without any problems ??

I'm looking for something maybe 3 inches...... 4 seems to be a bit much...

Anyone have pictures of your exaust tips???

My belanger cat back 3" came with chrome tips that must have been about 4". They wouldn't fit the hole in the side cover without rubbing. I didn't use them. The 3" pipe fits without a problem.
I think the chrome tips probably would have fit if everything was lined up perfectly. The muffler brackets had to be fabricated and welded on with the cat back kit that I got from PartsRack. The turnouts had to be trimmed and welded at the proper angle too. I was able to get the kit on the car and I like it but there's a lot of cutting and fitting to get it installed. Getting it just perfect would seem very difficult.
Someone will probably point out what I did wrong and they will probably be correct.
