So today I completed the install of a new exhaust system on my 72' 240z. It has the stock L24 with no mods. I swapped a motorsport auto header out of my 75' 280 into this car. It is the 6 to 1 style header. So here it goes...

I have a header, out to a 2.25 inch pipe with about 10 inches to a Glass pack (Bullet Muffler). From this muffler it does 2 bends to a Turbo Tip! This is actually a twin tip that has been filled with glass. This whole set up from the header to the tip cost me $80 USD. The header and Tip I had, So the collector and the bullet muffler with the tubing made up the rest of the $$$.

I am writing this to let you know that I have almost no loud res. in the cockpit. It is actually quieter than the old stock manifold with the turbo tip. I was told by 2Many that the bullet muffler would do the trick! He was right. One down side is the Glass packed filled twin tip is actually only 1.34 inches in diam. I would like to find a 2.25 inch tip to replace this one.

Thanks

I have seen lots of good exhaust tips in various sizes in the Jegs catalog.

I have seen tips in this diam, but this is an actual muffler in the tips; the inlet to the twin tips is only 1.34 and I was hoping to find a 2.25. Do they make these tips/exhaust with the 2.25 inlet?

I think they do, but Summit's catalog doesn't list the inlet diameters, nor do they list a part number for some odd reason.

They have Pacesetter Monza Tips with the resonators, single or dual outlet. Single is priced from 23.99, double from 29.99.

You could call their customer service line and ask them, 1-800-517-1035 and I think that is 24/7 too...

i priced out a mandrel bent stainless steel system for the Z. all parsts from jc whitney. and with muffler which is about 60-90 dollars the most the system would cost me is 170 dollars!!
