NOT Happy with Pypes SGF63 67 Firebird
After laying under my '67 Firebird for hours and hours over the last few months trying to get Pypes system lined up correctly, I finally got fed up & took my car to a muffler shop.
What should have been a quick install took close to 3 hours!!! We finally figured out that the pieces that were welded at the factory, were welded wrong. So not only did I buy a $600 "bolt together" exhaust system, but I wasted a minimum of 6 hours of my time and had to pay a shop $200 to fix a manufacturing issue.

Grr! Much like Israel has mandatory military service for all, I think everybody who wears the title of "car guy" should be required to do an exhaust install at least once in their life.
You haven't lived until you've wasted an entire weekend and a significant piece of your good health under a car, inventing 2-3 new swear words along the way. I feel ya, brother!

Care to elaborate exactly what was wrong?
I've used a half dozen of the Pypes systems and nothing on them have ever been welded except the "X" portion itself which isn't very big. The rest of the system is a slip fit design. The one you bought doesn't come with mufflers. Did you buy the correct offset inlet/offset outlet mufflers that this system is designed for? Not questioning your issues, I'm just trying to understand exactly what was wrong. |

The two 'over the axle' pieces from the muffler back were originally 4 pieces that were welded together.
When mine were welded, they were 'clocked' wrong so that if it lined up with the muffler, the rear piece would be in the fender. If I lined it up with the rear piece, the end that goes on the muffler would be pointing up to the floor pan. On top of all of that, the hangers had to be modified to work also. The weld locations are roughly marked in the attached pic.

I have similar feelings about the Pypes SGF70 system for my '77. It isn't even close to fitting the car as delivered, and requires several hours of needless cutting, fitting, cussing, etc.

Now the SGF70 I've bought 4 of them and never had any fitment issues with them at all on Nova's, my Firebird, and Camaro. Absolutely love that transverse system, great sound quality, no drone what so ever, and it picked up the car at the track.

On my '77, the drivers side mid pipe that goes over the axle is 1/8 inch from the rubber brake hose. The tailpipes are a joke. There are too many separate parts that make them up. There is no reason a splitter tailpipe could be manufactured, since there are potentially several 1976-81 cars that can use them. I am disappointed in it after spending almost $800 for the system, tips, band clamps, adapters, etc.

The brake hose back there is always a problem on the transverse systems. I've used Flowmaster, Dynomax, and Pypes, and they are all close because of the over the axle pipe needing to make a 90 degree bend there to enter the muffler. Flowmaster was actually worse because those pipes went into the top of the transverse muffler (goofy design) But just the way these systems are. It's a relatively easy thing to fix though.
Not sure what you mean about the separate tail pipes being too many pieces. All the SGF70's I've bought always had 1 piece tailpipes, then you install the tips you want. I never ran the splitters though, my Formula is a 70 so before those things were used on F-bodies. I bought their polished stainless angle tips that protrude under the rear valance. All fit fine. |

Matter of fact I have the car on the lift now with the motor out. I could snap a pic of the exhaust and how it fit on mine, but likely wouldn't help you.

Thinking about it, sounds like we might be getting to the bottom of the issue.
Your also saying your tailpipes are more than one piece which has me wondering if they have recently changed their design or manufacture process causing these issues, because like I mentioned, the systems I've bought always had 1 piece tailpipes. Could be the difference. |

The tailpipes in the SGF70 kit must be cut, these welded on AND the splitters welded on. That is a lot of welding for a simple tailpipe.

Yeah that's more welding, but on a bright note, I like the adjustability that would provide to get those splitters positioned "just right"

Was reading this section and couldn't help but chime in. A few years back I was installing a Pypes system on my 67 GTO. Did then and still do have issues which are mainly, but not only, due to the fact that the system, as designed, sat WAY too low with stock height and (new) stock springs. I was replied to here by a member who said he worked for Pypes and was very defensive about the whole thing (just sayin'). What prompted this response was a comment I read regarding welds on their pipes. The system I bought (through Summit) came with a butt weld right on one of the over-axle pipes, like they were a couple feet short to make up the pipe and chose not to use a piece long enough so as to eliminate this weld, very disappointing to see. This, and I still can't figure out why, is what I found on my system and the folks at Pypes had told me it is common practice. Yes, I was told the warranty was still good for the weld, but why leave an unnecessary weld to chance a later problem for the sake of not using a piece of strait pipe that is 2-3 feet longer to start with??

To answer the last question:
I bought the system from Pypes directly & picked them up at the Daytona Turkey Run. I have been emailing back & forth with tech support and just got off the phone with them. I think we are on the same page as far as what the problem was & he is going to look at some of theit kits to get a better idea of what I'm talking about. The attached picture is from the Pypes gallary of a 68 F-body with the 3" kit. It clearly shows where the tail pipe is welded like mine. The pipe in front of this one was also welded & both were 'twisted' a little too much when welded which threw the ends out of alignment.

Is there a place in this forum to suggest production changes with Pypes exhaust products?
After my and other's lackluster experience with the SGF70 kit, I'm hesistant to recommend any of their products. I feel a better job can be done with the kit.

Here are a couple of shots showing where my Pypes were welded.

My hats off to anyone that make these kits fit on their own. Not just PY issue IMO. I bought the RARE kit and its the same story with the tail pipes not being clocked correctly. I spent a few hours on the ground trying to figure it out and said screw it and took it to a muffler shop.
I wasn't happy that they kinked up one of my mandrel bent tail pipes to make it fit but I was happy that they put it all in a few hours. Well worth the money to have it done IMO. |
