Topic: Complete Exhaust Systems

[LANCER]

Who sells a complete exhaust for a 1977 Trans Am ? I know of two places but am wondering if there is more. The ones I have heard of are Ram Air Restorations and Pypes. If these are the only two out there which one makes a better product? Is a person better of with a dual exhaust into one muffler and dual out or duals into seperate mufflers? Is there a clearance issue when using either of these systems? I am using ram header manifolds and the engine when finished will be about 380 HP. Thanks,Lance

hmm i cant say which one makes a better product but i do like the whole pypes system....i ran it on my 79 and my 78 i had....dont like any of their brand mufflers though....flowmaster, and magnaflow both have systems out now..and when i finish my 79 im putting it on....but as far as clearance issues the pypes was a perfect fit everywhere...mine had the x-pipe and when it ran down the body it was tucked up rather nicely in the driveshaft tunnel....

What Pypes system did you use? One muffler or two? Do you recall the part #? Thanks

i used the dual muffler system, never cared for crossflow mufflers

Were the mufflers located under the car or just one by the rear axle? I have been to pypes web site but I am not sure what system you are talking about. Would you have time to go to there site and find out what system it was?

So did you go with the SGF30 system?

[eroc022]

no i bought the SGF10s system with mufflers but i recommend the part number you have and pick up your own mufflers, its 2.5 offset in and 2.5 offset out

I used a Pypes system on my 76 with the race pro mufflers and X pipe and it worked great. The Pypes system is a 2-1/2" mandrel bent system and it flows better than a 3" regular bent system. If you check flow rates on mufflers the pypes flow much better than the flowmasters.
