Had the car on the lift to install a new set of MT Drag Radials, and I realized my one muffler shit the bed... Exhaust system is aftermarket but has been on the car for the past 20 years. Car only has 14K on the clock.
I did my research and it looks like the Pypes, 2.5" cat back system with the Race Pro mufflers is a good value for the money for a complete bolt on system.
Is there any other system that is cat back, bolt on, 2.5", that I should look at before I pull the trigger on this Pypes system? I don't want a loud exhaust...
-
the Pypes is the best bang for the money. They have about three different mufflers. You can go to their site and listen. Turbo cars are always quieter than regular cars
-
Steve~ I talked to the guy at Pypes that designed the system, at least that's what he told me... He recommended the Race Pro muffler as it's the only "straight through" design of the three. I don't want a chamber type muffler, on the GN. Flowmasters are good on the BB Camaro, but not so on the turbo car. I want to hear the turbo spool.
-
I agree completely
Not sure I agree that completely :D I hate FloMasters totally and think they are too restrictive for a serious car-of course, take it with a grain of salt because I have Walker Race Bullets on my 440....

Are you looking at the stainless or aluminized system?
I'd suggest stainless as it will out live the car... your 20 year old system was probably made out of mild steel which is why it rotted out.

I was looking at the 409 stainless system that Kirban sells. I don't like the stainless tips, but I can always pain them black.

I overlooked the RJC because I was after a 2.5"... Now I need to take a closer look.
The 304 is certainly better quality than the 409. I'll give Jason a ring and pick his brain.
Thanks for the link.

Just installed the Pypes system....real ly like it

Any issues with the install?

Not to many. Glad I had a lift. The pipe that goes from the cat back had to be trimmed to fit, had to cut about 2 inches off one side and 1 inch off other. Also the flange is pretty thick at the cat and kinda hard to get nuts started. Also the tail pipes mount solidly to the frame. They dont supply the bolts but they do supply the poly bushings. The holes in the frame you use are just out of finger reach so thats a challenge.
I do like the sound but a but "droney" at 60 mph. I know Flowmaster's are no good for performance on these cars but I did like that sound much better.
Hope that helps :cheers:
-
I have a lift, so I'm good there. So much for a bolt on system if you had to cut the pipes???
In the pictures I've seen of the Pypes installed, it looks like the tailpipes hang down a bit under the body. My current tailpipes are 1" below the body. Are your more than that?
-
Did the Pypes system exist 20 years ago? I was thinking the GN kit was a fairly recent thing from them.
-
last few years...

strange your car drones with that straight thru style of muffler...they are usually pretty much drone free.
You prefer flo masters sound? Worse sounding mufflers I have heard and always associate them with kids that wear their ball caps backwards and hope to grow up to be UPS truck drivers because they like the sound of UPS trucks
-
I like flowmasters on lifted trucks but I'm also young. I know that I wouldn't want flowmasters on the tt though. I like the comfort of no drone in them.

i also have that damn drone on my car.
My set up is 3" DP into a 3" X 2.5 Y into two 2.5 12" or 14" Summit or Dynomax bullets.
On long drives --- To quiet the drone down a bit i put a cap on one of the tail pipes. Looks like crap but in a hour plus drives its worth it.
-
The larger pipes tend to accentuate the drone.
I run 2.5" on one car with Hooker Max flows or whatever they are called. The other one has 2.75" pipes and 2.5" Ultraflos. Neither one drones.
The three inch systems, or larger, that I have seen all have that hollow sound that I don't like.
In general, the chambered mufflers like Flow Masters are restrictive compared to the good straight thru units and generally start costing hp past about 500 hp.

No, they hang down about that, they are up much closer to the body than the flowmaster system was.
With the lift cutting was no biggie, I had the first pipe mounted and then you can test fit the rest, mark where you need to cut and bust out the sawsall. I didnt expect to have to cut either but other than that the rest fits very nice
-
Perfect, thanks for the heads up.

usually helps to start at the rear and work forward

I can't agree more. The 4" system on my Buick drones, the 3" dual system on my MCSS drones and the dual 3" system on our TBSS droned a bit before I built a 3" catless y-pipe... now it really drones over 70mph! And that is through a huge Magnaflow with an internal x-pipe. The Camaro is catless and is dumped before the axle (no muffler)... and it drones too.
The wagon has a 2.25" system on it with Flowmasters, not preferred by any means. But! It might just make for an enjoyable combo for the family car... and if I want drone it came with some electric cutouts that I can open at will.

On the "stock" style pypes -very quiet, no drone to speak of- drove 800 mile trips.
If anything they seemed a little short tho- not too long at all.

How about a video with sound on your new system

I'm part Scottish I cobbled together my own 3 inch single with a Dynomax Ultra Flow.
Love the way it sounds at Idle and WOT there is a bit of a drone at 2000-2200 but most of the time it sounds pretty good to me.
I'm kind of blind and partially deaf from age but I'm still a kid at heart especially when I drive the Buick!
