GHL exhaust installed on C2

So I was one of the 8 who got the $700 GHL exhaust and some friends and I installed it last weekend. I like the new sound and I feel that the system is continuously adapting to the new set-up. Initially the exhaust was pretty silent. At >4KRPM my K&N Cold Air Intake gets so loud that I didn't hear the exhaust initially. However, over time I heard the exhaust more and more and I think the sound will still change. I imagine to feel an improved throttle response at already 3KRPM and when the ECU has finally adjusted, I may see more difference. The exhaust is fine; There's no resonance / droning; I think that the car now runs even smoother at idle with a cold engine (maybe the exhaust is now louder than the engine) and when I cruise at 2.5-3.5KRPM it's only slightly louder than stock. However, when I go WOT, then the system awakes and sings up to redline with the CAI adding more music at 4KRPM. I like it a lot! Holding one can of the old exhaust and one can of the new one at the same time, I'd say that there's a difference of 10-15lbp in weight for 1 side, so 20-30lbp for the whole system. The new cans are also smaller.

hwk I too took advantage and just received my shippment Saturday. How was the install? would I be able to do this myself if I ran the car up on ramps?

I'm one of the lucky 8. Can't wait to get it install now that you have great feedback from it. Thanks for sharing

Hey, can I get your left stock tip? I don't want my GHL tips. I'm wearing mis-matched tips right now because my right(passenger side) tip doesn't fit right.

Dominick, it's a pretty straight forward install (although I was lucky that one of my friends was a mechanic and we had a professional lift). The muffler is fixed with 4 screws to a plate and there's a double clamp that connects the muffler to the pipe that comes out of the cat. Last but not least, there's another clamp for the end tip. Don't try to take the mounting parts for the plate off. This is where we got confused in the beginning. The plate stays fixed to the muffler until it's completely off. Then you put it on the new muffler.

Sure, you can get both stock tips for free. Just PM me when and where to meet. Fitting the tips is a pain. My cheep aftermarket tips (not GHL tips) are equally made but the driver's side exhaust sticks about 1/2 inch further out (that's by design and true for the stock- and the GHL exhaust), so you can never match the look of both sides unless you have uneven tips.

Congrats!!! I got mine back in January and I abosolutely love it. After reading your post now I want a cold air intake, too.

let's have a sound clip........ hey do these add hp?

waldrondigital posted a GHL sound clip thread on his 3.4l engine . I'm never sure about HP gains with aftermarket stuff but the mufflers sound stronger!

thanks.....

I love the sound of my GHL exhaust. At the very least you get 10% hp increase due to improved power to weight ratio.

This might be a silly question since the only thing that came in the box was the mufflers snd the tips, am I to assume that I will use existing mounting hardware from the OEM cans?? or do i ned to buy stuff

Dominick, you do only need the mufflers. All screws, clamps, ... of the stock exhaust can be re-used.

thank you Almost a panic attack there

Please realize some of the existing nuts and bolts will be difficult to remove particularly where they are repeatedly heated and cooled. Just spray them and let them sit for 10-15 minutes and then be gentle to not strip them. Other than that yes they are nice sounding, expect no additional HP.

OK Mine are on!!! A bit of a problem with some rust clamps but fairly strasight forward install They sound pretty good and haven't caught any resonance as of yet. Can wait to see what they sound like as I drive her more and they start to settle in!! Thanks for the info everyone

Great to hear that Dominick! You'll love this exhaust. We had some nice days here in Northern Virginia this week, so I drove around quite a bit with the top down and did really fall in love with the new sound. I think it changes over the first couple of days. Especially when I'm cruising around with 2.5-4.5KRPM when the CAI is not too present, the exhaust makes the car sound as it should be. I could not switch back to stock anymore. Cheers, Harold

CAI is next After reading some of the other posts I think I'm leaning toward the EVO

Anybody want to sell their old stock cans, my brother is trading his car in and needs a set. PM me tia Chris

Chris, I am installing my TechArts exhaust on my '00 Cab this weekend and depending on the sound, if not too loud and I like it on the car then you can have my old cans for free if your Brother is willing to pay for the shipping cost. I will let you know next week with a PM. Cheers,

Thanks Botsy67, I'll forward the info to Doug (DJ996)! C

Thanks Chris, PM sent to Botsy67.

I'll call the shop - If there still there and you want to go get them their yours

Thanks Dominick, which shop did you use? C

If I can get some stock cans I'll make someone a smokin deal on my 1 year old GHLs....

Hello DJ996 I see your comment about selling your GHL cans that are 1 year old. I would be very interested. my c2 is a 99 coupe. my 2 sons in college =very tight budget ! so your suggestion would be great for me.

Hey chris I used a place call body motion in Asbury Park NJ If you want call on monday (closed weekends) and ask for Ace. He helped me out. I think there gone but you never know maybe they have other laying around since he is Porsche specialty shop

Doug, Sorry for the late reply, but I sent you a PM... I should get back to you later today regarding my TA install. If all goes well, I should be able to send you out the stock cans next week. BTW I am in Allen (TX) about 13 miles NE of Dallas Forth Worth, not too far from Houston, I guess Thanks, -Bao.

PMs sent to Botsy67 and Seeeu911

Thanks Doug ! Cans were in excellent condition, well packaged. My son and I stayed up late last night installing them. the sound is so much better than stock. Thank you again.

Awesome, glad I could help out another Rennlister.
