exhaust

[zumwoll]

I have a 2.2 with a Bursch exhaust. To me it sounds puny. Local tech tells me that it is vintage and has lotsa back pressure. He recommended having custom pipes made that bolt onto heat exchanger pipes and run those in to a Magnaflow dual input/output muffler. At $375 it seems kinda spendy. Granted that that from the stock pipes after the pipes are 2" I can't imagine that there couild be a big difference in performance alathough some in sound. The reason that I question increased perf. is that the car leaps in first and is pretty strong in second and after that is unremarkable. I would think that if there were excessive back pressure, there would be poor first gear and second gear perf. ??
ALso, Wayne---since I know you read most of these posts---do you think I would see a difference if I just upgraded to teh Sebring dual that you offer?
Sorry about the long verbiage.

what year car?

is the 2.2 a /6 or a /4??

Mike:
2.2 is a 2.2 bored. Actually it is a 2160, but every one rounds it up to 2.2

[zumwoll]

2.0 and 2.2 is 4 cyl

carbs are FI?

[zumwoll]

Dells tho I believe I have most of the FI stuff. Personally for performance I prefer the dells.
I have surfed around and saw something called Tangerine however at $1000 it was out of the question.

You really arent going to see any gains out of the exhaust unless you do some serious headwork. Stick with the Bursch.

If you want to lose all of your heat, a real tuned header system can net you some power. The Tangerine Racing one is the best of that lot. European Racing (George Narbel in Nevada) and Triad West Performance in Washington make less-expensive headers that are less effective than the Tangerine one (they seem to be roughly equivalent to each other). Kerry Hunter makes one that is cheaper yet and less effective, but still makes more power than the stock system.

Apart from that, I wouldn't expect any significant gains over your Bursch from just replacing a muffler on the stock heat exchangers. At least, not if the muffler/collector are in good condition.

Living in the high desert I am a little reluctant to give up heat. Do any of those ceramic heater actually do the job. I paid $100 for one that was next to useless.
But thanks for the tip on the header systems.

To echo the above, if you still have D-Jet cams and stock heads with the Dells, that is your limiting factor, not the exhaust...not to say that a good header+muffler setup would not get you any gains. It most likely would, but that is a pretty spendy way to pick up just a few HP esp. since you would lose heat and gain noise.

I currently have Jet-Hot coated Bursch headers on my -6 conversion (and they are fine) but I have never been a fan of their muffler setups at all, FWIW. I actually had one on my last 73 2.0 and went back to a NOS factory muffler.

The factory muff actually is quite good. Most aftermarket 914/4 muffs are less than optimal for a stock motor.

[Jared at Pelican Parts]

exactly mike. The factory 2.0 muffler is about as good as you can get
