Re: Pypes exhaust on my 70

The Pypes SS tips look great. Pypes makes a really nice system. I have the same system on my '70 only with 18" Race Pros. How do you like the Violator mufflers?

Sweet looking ride... Did you know Pypes carries a lifetime warranty on all of our systems...?

Re: Pypes exhaust on my 70

An interesting post. I have Hooker headers on my newly acquired 70 SS 396. That sounds like a good thing but I hate the crowding of the headers (long headers) and they seem to leak. The passenger side hits the rear lower control arm mount. There is no room to work on anything with them in there. So I'm thinking of taking them off and going with stock exhaust manifolds and a stock or slightly non-stock exhaust. I looked at the Pypes exhaust products but am really new at this. I would appreciate some feedback from you on this forum on what to do or not do.

Re: Pypes exhaust on my 70

Melb-Mike,
I'm with you regarding headers. I decided to go with manifolds instead of headers on my SB Chevelle and glad I did. Too much hassle with long tube headers on a street driven car, especially on a lowered car. Hence the popularity of 3/4 length headers, which are generally regarded as only marginally better than manifolds. Pypes, Magnaflow, and Flowmaster all make complete 2.5" & 3" systems for your SS396, and also offers manifold down tubes and SS style exhaust tips. classicmusclecarexhaust.com seems to have everything you need.

Re: Pypes exhaust on my 70

Shovelrick- Tell me about the Violator mufflers. I know they're aggressive but do they calm down when cruising on the highway? Do they drone at all?

Re: Pypes exhaust on my 70

I haven't been on the highway yet (still working on the car) but I've been up around 45 mph on U.S. 19 (has lights) and I'm happy, I also have Dynamat Extreme & FatMat on the floor, no drone either

They donít really drone, just loud AF. Mine were dumped at the axle.

Rick, I use these tips with stainless band clamps. They look good and don't say Pypes on them. Cheaper too...

Re: Pypes exhaust on my 70

I have the 2-1/2" Pypes system on my 69 el camino with 454.. I ended up removing the X and ran separate pipes and also swapped the mufflers to Dynomax Super Turbos #17749.. It sounds so much better!! It has a more traditional Big Block Chevrolet tone now..

Re: Pypes exhaust on my 70

I'm running headers and Pypes 2 1/2" stainless with Race Pro mufflers and no X pipe on my '69 L78 SS. Sounds great at full throttle but a bit louder than I'd prefer at cruising RPM.

Re: Pypes exhaust on my 70

A real good performance cast manifold is available thru Sanderson, thick flanges require no gaskets, I use a bit of gray sealant with excellent results. I am through with long tube headers and their limited life and propensity to leak...

Re: Pypes exhaust on my 70

I just started putting the Pypes 2.5 in. system on my 69 yesterday, did anybody have to cut the pipes between the muffler and the X pipe? It seems my X is to far forward to allow the front pipes to go though the transmission cross member where the stock pipes go. The instructions mention that the pipes may be cut shorter for proper placement.

Thanks, Shaun
