There's only a tiny bit of truth to my comment... which was predominantly geared toward what I had to work with, based on the post.

That being said, Ive been working on GTO's for more than 30 years, and Ive also been a certified welder for most of that time. On my current 67, I didnt like the fit and finish of the Pypes system... however, since my uncle was the one who installed it, I can't say how much of that was his fault.

My only real gripe is that the exhaust has been FAR TOO quiet, since day one. Everyone said it was the X-Pipe, so I removed it... which was an improvement, but barely. Then after months of confusion with the system, I finally called Pypes and asked for advice. They INSISTED that it was the mufflers.

Well, they only make three mufflers and the ones I have are the middle, so I found that to be ridiculous... and very hard to believe. So I wrestled with it a few more weeks.

Finally I put Flowmaster 40's on it, which are the 2nd loudest mufflers that Flowmaster makes. It's STILL ridiculously quiet... Which leaves me with a fairly aggressive 67 GTO, and I get laughed at by the hotrod crowd because it's so quiet. People with 4 liter engines are twice as loud.

It's a 400, 30 over, ram air roller cam, 800 CFM carb, K&N filter, edelbrock manifold, fully welded exhaust... and a 80 mph, I can have a normal conversation in the car. AND THERES a 4 inch hole in the floor from my Tremec!

But my last GTO wasnt half as aggressive and it had manifolds with cherry bombs, and it was much louder.

And my 70 Vette has a mild 350, stock manifolds, 2 1/4 duals and cheery bombs, and it's loud as HELL!!!!

So it's a mystery to me... and now one that I can believe could be due to the Pypes... but nevertheless, here I am.

That being said, I dont like that they said it was the mufflers, when it was not, and that's my only real beef. Im on my 3rd set of mufflers.

You should do the cutouts then, one drive with mine so far and I love them.

I've found ordering from a vender is usually a better alternative than from the supplier, and is often cheaper to boot. I have a Pypes system on mine that I ordered from Summit. I have what should be their quietest mufflers on mine and an X pipe and it's still pretty loud. I had a V6 Dakota that was way louder but that wasn't what I was going for on the LeMans.

My Race Pro mufflers are the worst sounding mufflers I have ever heard

A good friend installed a complete Pypes system on his '65 about 12 years ago and it's flawless. Great fit, great sound (no drone on long trips, can hear the radio), and he added cut-outs. I was impressed with the fit and quality.

Check out my YouTube channel Baaad65 and see how they sound, I like them. The cutouts are on there also.

I have a 2.5" set of Pypes with an x-pipe. The original install was done by a shop that decided to bend the down tubes and x-pipe to make them "fit better". Apparently better is a subjective term. So I replaced the butchered down tubes and x-pipe with new ones. The replacements fit perfectly, no additional bending needed. I ordered the original kit and the replacements from Summit. I did talk to Pypes tech service a couple of times and found them helpful. The replacements were purchased last summer and Pypes did not have the parts in stock so the rep suggested a retailer. So I cannot speak to ordering them direct. Keep us posted!

I love the way your car sounds with the cutouts, but my point was, my cars were ridiculously loud, without them... until I got this Pypes.

Ive been putting loud mufflers on fifty different cars, trucks, and motorcycles, since 1987. I really thought I had it down to a science. This Pypes thing has me stumped.

PM me the details. Id like to see it.

@Baaad65 had the same experience. Which makes mine even more perplexing

It's Verdoro Green and in the General Classified section of this site, I MAY have finally found a buyer, too soon to tell.

That's the kind of feedback that I usually hear about them.

Ive almost ordered a new system from them, a few times, but Im a tad reluctant until I know why mine is so quiet.
