DOOMID Posted September 19, 2002 Report Share Posted September 19, 2002 Does anyone have this exhaust system? Any one with pictures, feedback, opinions, pros/cons....am thinking of installing but thought to ask first. Link to comment Share on other sites More sharing options...
cudabnu Posted September 19, 2002 Report Share Posted September 19, 2002 Kelly had a killer deal on a 3" exhaust sys (less cat and muffler) for $295, i'm not sure if he's looking for 1 more person still. it is under the group buys, but if you already have the HK$, then install it, I've never heard anything bad about them!

Questsi Posted September 20, 2002 Report Share Posted September 20, 2002 I have the HKS catbback on my car...........It's been good to me but I'm getting Kelly's 3 inch Link to comment Share on other sites More sharing options...
SimmDawg Posted September 27, 2002 Report Share Posted September 27, 2002 I had the old HKS Sport with the downpipe on my old '87. I LOVED it!! It sounded great, never gave me any problems, flowed well. Nothing but praise from me!! I would recommend it. I would also recommend some Q-pads or dynamat in the rear hatch to cut some of the noise inside. Link to comment Share on other sites More sharing options...
Guest Posted September 27, 2002 Report Share Posted September 27, 2002 http://www.optauto.com/webstore/product_in...36&back=yes Kelly's exhaust is probalby nice, but HKS might have a little more research and development. Link to comment Share on other sites More sharing options...
Boosted_One Posted September 27, 2002 Report Share Posted September 27, 2002 Kelly's 3" exhaust would kill an HKS exhaust. I've ran the HKS and it works better than stock but no where near what a 2.5" or better yet 3" will yield The HKS isn't even 2.5". Link to comment Share on other sites More sharing options...

FontanaTSI Posted September 30, 2002 Report Share Posted September 30, 2002 Yeah, ya gotta go 3"....and Kelly's system at that price, should fit the bill perfectly. I've had a 2.5" system and a 3" and made a significant improvent in power with the 3" over the 2.5". Just my .02 Jerry Link to comment Share on other sites More sharing options...
ConquestTSi Posted October 1, 2002 Report Share Posted October 1, 2002 Even with just stock engine (well mainly turbo)? Link to comment Share on other sites More sharing options...
FontanaTSI Posted October 2, 2002 Report Share Posted October 2, 2002 Yep, even with the stock turbo. I was running 16 psi though. 3" is definately a must especialy if you plan on going with a larger turbo in the future. I know some people swear that 2.5 is the way to go but I've tried both 2.5" and the 3" was the clear winner. Later, Jerry Link to comment Share on other sites More sharing options...
artinist Posted March 3, 2003 Report Share Posted March 3, 2003 i had it. its nice and well made but the pipe diameter is probably going to limit HP to about 300hp. the worst thing about it is the sound. its way to quiet. barely louder than stock and the tip is wimpy looking. I would go with kellys also. Link to comment Share on other sites More sharing options...
Ratmtattat Posted March 3, 2003 Report Share Posted March 3, 2003 Weird, I picked up the HKS cat-back from TEP, and it's definately 2.5in. And the sound from it is actually pretty loud. Maybe the full exhaust is a different diameter? Link to comment Share on other sites More sharing options...
heefner Posted March 4, 2003 Report Share Posted March 4, 2003 HKS is 60mm wich works out to be 2.3" not quite 2.5" also a cat back system will not work as well as a full 2.5 or 3 simply because of the very restrictive down pipe. Link to comment Share on other sites More sharing options...
Questsi Posted March 4, 2003 Report Share Posted March 4, 2003 I had a TEP downpipe, stock middle exhaust section, with gutted cat, and HKS catback exhaust. The car was quick and the exhaust had a nice rumble. Now I have a full 3 inch. No comparison whatsoever. 3 inch is the way to go. Link to comment Share on other sites More sharing options...
chicagoslick Posted March 6, 2003 Report Share Posted March 6, 2003 I have the old version of HKS cat back that was 65mm. These are probably getting hard to find. Question? Has anyone encountered problems with clearance at the rear near the axle? I have had my car in the exhaust shop twice to try and fix the rattle and rub. I've had the exhaust ovaled to help with clearance, no luck. I would imagine 3" has to be even tighter. A little of background info on my car might explain the lack of room. My car has the tokico struts installed and suspension techniques springs. Also using suspension techniques front and rear sway bars. Additional 150lbs of weight in the rear of car ( stereo equipment ). (Car lowered by almost 2" with suspension and weight additions) Any ideas and fit of the 3" on similiar suspension layouts. thanks in advance, gary Link to comment Share on other sites More sharing options...
mstieg Posted March 10, 2003 Report Share Posted March 10, 2003 I have the 2.5 HKS catback on mine. Car came with it. Not sure on the muffler, but it sounds great! I love hearing it purr under from the pedal. 3 inch is prob. a bit better, but I'm in no condition to change. The end pipe did barely rattle against the gas tank when I got it, but was quickly bent a wee bit to eliminate that. You'll want at least a 1/2 inch clearance w/ all pipes to leave room for any vibrations so that doesn't happen to you too. Good luck w/ whatever you decide on. Bed time....I'm exhausted. -Matt Link to comment Share on other sites More sharing options...
svo Posted March 10, 2003 Report Share Posted March 10, 2003 I've got an Hks system from turbo to tailpipe and have loved it. Best thing about it, is it's all stainless steel... it will never rust. I also bought Kellys 3"... I hear and believe there is no comparison. The Hks was good for 18 hp increase. And... there is a catback system in a local junkyard on an 89 located in So. Cal.
