CAT Bypass Test Pipe?
Anyone have any experience with one of these on an NA...its just that my current exhaust sounds anemic and I was considering a Bursch. Our host PP indicated that they dont have a Bursch for an '86 (Perf Prods does, sorry Wayne...), however, PP did say that I could purchase a GHL for $317 +...dont know if I want to spend that much only to later decide I dont like it...any suggestions?

I've used a Bursch test pipe with the Bursch header on an NA for many years. I don't think it does anything particularly good for exhaust sounds. If anything, the sound, with header/test pipe & OE muffler, is tinny and whooshy, if you know what I mean. Exhaust note may be different/better with just the test pipe and stock header or with a free flow muffler, I'm not sure.
However, if you can live with the sound, the Bursch system might actually improve performance a little on your NA, complementing the cam and compression increases for a little more punch at higher rev's.

Im running a Bursch Header and test pipe with a B&B catback exhaust on my 87 924S, I like the way it sounds, throaty at low RPM and up around 4500-6500 it sounds like a F-1 car kinda cool, I havent had any problems with it and I noticed a torque increase threw the RPM range, I think it also helped with my other mods. Let me know if you have any questions

Alright,
I went for it. Had the cat replaced with a test pipe (the car is being used for off-road porpoises only ). I like the low rumble. Is this possible, it seems to rev a little quicker???? Maybe the CAT was constipated?... I like it... When is the next So Cal meet? I'd like to compare it or at least get some objective, first-hand, onsite, opinions from some fellow owners...(this excludes YOU Ronin, unless YOU are planning to come down here so that my pet can give you a good ole fashioned Llama azz whuppin...)  Bob

and what's with you suddenly dissin' porpoises. you got a problem with seaborne mammals? well do ya?!? and shame on you for using a test pipe for noise instead of performance. tsk tsk I've been thinking of going the test pipe route myself once I start doing performance mods. the noise shouldn't change much due to the turbo
