Hi all,

Sorry I have a newb question but i'm in the process of putting together a GT3 style exhaust system for my 4S. But I'm having a hard time trying to justify paying $500 for some tips so I was wondering if I could just have a shop make me one out of some tips I found on EBay here: http://www.ebay.com/itm/Silver-Tone-...af2f77&vxp=mtr

The only thing is they are way too long. My question is, can the muffler shop just cut these tips to shorten them and weld onto the polished section? Or can they only weld to raw steel?

 

Seems like your muffler shop would have the answer.

 

those ebay tips look like trash. you get what you pay for.

 

When the cut & welded tips fall off or rust out, you'll have your answer.
Your driving a Porsche. Not a Chevy.

You're doing a very expensive GT3 exhaust conversion with fully custom pipes and a new rear bumper, but you want to use Ebay exhaust tips?

 

Woow be easy on the guy daaaammm he asked a simple question.

 

Those would probably discolor from the heat of being re-welded onto another pipe.

 

I'm probably going to get blasted for posting this, but I was forced to use some eBay tips on my wife's C2S after installing a Vorsteiner rear bumper.

Here's the story. I purchased the Vorsteiner bumper used from this or the Rennlist forum Marketplace. The seller did not do a very good job of cleaning it prior to shipping and I noticed a lot of carbon and black soot on the underside of the exhaust openings. If you look carefully at the attached pictures, you can see why. Exhaust tips should really protrude slightly beyond the rear bodywork in order to not create a black mess under the bumper. The Vorsteiner bumper is thicker than the OEM bumper in this area and this sculpted section was painted black originally, either for the look or to help with the black build-up that was occurring when running factory tips that didn't extend to the edge of the bumper of just beyond. The other problem was that the openings were wider than the factory tips, which made the tips (even the dual round S ones) look too small. I looked everywhere for a set of Porsche tips that were long enough to get just past the edge of the bumper - FVD, Fabspeed, Maxspeed, Dansk, Agency Power, Summit, Borla, etc - virtually anywhere I could think of, but total length from the input connection to the end of the tips was always 4"-5" and I needed more like 7".

I found a Stainless set on eBay that had a 2.25" inlet, an oval outlet of 6"x2.5" and a total length of 9", but about 2" of that were straight lead in, where if I cut-down the lead in pipe by about 1.5" I could cut slits into the remaining 1/2" and use a strong stainless exhaust clamp to attach them securely without having to weld onto the factory exhaust, and although they're still just a little longer than ideal, they look quite good. I was able to angle them to follow the non-horizontal curve of the bumper openings and the oval outlets are also wide enough to fill the larger Vorsteiner openings. With the Gundo Hacked mufflers the car came with, it sounds quite good - very deep and throaty.

Quality of the tips is actually better than I had expected and they've been on about 6 months - position hasn't moved and they still look like new. They're on my wife's daily driver so they're getting plenty of use (lots of heat cycles), exposure to rain, etc. They're made by a company called Flo-Pro and they've been in business since 1981.

Although I would have preferred to find proper Porsche OEM or aftermarket options, regardless of the cost, they just weren't out there, but not all non-branded tips on eBay are junk, you just have to do your research and make sure they're made by a reputable company with a history and not imported and of crap quality.

 

not to hijack but that is an excellent looking S...great adaptation of turbo tail, looks to be a working model... is there a thread on it anywhere?

 

There's nothing wrong with buying on eBay.
FabSpeed can be found thee.
It's what you buy and what you pay that matters.

 

I think we've all been there done that before. Going for the less expensive solution first, ended up not happy with it after the fact, then later on forking out the extra money anyway to replace it with the right solution. Sounds familiar?

 

kkswow12, thanks for the complement. I didn't actually write a thread on it, but have made a few posts either here or on Rennlist (same user name) if you look-up all my posts, and yes, it's fully functional - raises automatically at about 80 MPH, drops automatically and also can be manually deployed or retracted from the spoiler button in the center-stack.

It was actually very straight-forward as the wiring harness for the turbo engine lid plugs right into the connector where the previous wiring harness was connected. It has the power for the TT wing, cooling fan, light, etc. The only modification that was really needed to make it work was to change out the OEM airbox. Only the K&N and the EVOMS intake are compatible without doing a lot of customizing - I have a Fabspeed carbon one on my RUF R-Kompressor and had tried to test-fit that one first figuring that's what I'd use but because of the central position of the Turbo lid's cooling fan, there's not actually enough clearance without relocating the fan (it's offset in the non-Turbo cars). The airbox change is needed because you have to leave room to the sides for the hydraulics to extend down into the engine compartment when the lid is closed. Also, if you'll be painting it, you need a special spanner wrench to unscrew the hydraulic rams from the upper wing.

My wife and I are both very pleased with how the car turned out

Here's a couple more shots and a link to a Shutterfly share site that has a bunch more.
