So. Tonight’s progress was slow. Every bolt in the cat to silencer clamps snapped due to seized nuts. As expected tbh.

Another Porsche mug & Bose soundtrack.



Scrap metal.



Long bolt at front of silencer also snapped so I will angle grind off tomorrow. However. The new bolt is going to be a challenge, as the Designtek performance manifold is in the way. Hmmmmm. Will look at again tomorrow.

I am a bit worried about this comment from another forum member in 2018.

“Anyone that's fitted the Topgear X-pipe have you had to put longer clamps on compared to the standard ones? Where the link pipe fits to the silencer pipes.

Seems a very big gap with mine when offered up with current set up.“

Oh. And I think I might have solved the long bolt issue. They were in upside down maybe. This schematic shows the bolts entering from above.



Looking to replace all these bolts with stainless or titanium. Steel is just stoopid.

Thanks C11BRA & Phil 997.

This sounds like the TB and Plenum upgrade is was thinking about doing on my previous 987..i brought the IPD kit but sold the car before id had chance to fit....but their were divided opinions particaly around the loss of low down torque.

Think i'm going Top Gear Valvetronic and 200 cell cats


I had the IPD on my gen1 and also have it on my gen2 but you do need to get it remapped to get the best from everything. maybe the reason some say it loses power or doesn't work is that they either did it as a stand alone mod or didnt get a remap. its important to do it as part of a set of mods inc exhaust , many of these mods dont achieve optimum as a stand alone mod

No cats. It has Designtek bypass pipes & lambda extensions.

Probably why the current set up is so raw!


Christ that must be loud..

Also not good for Low down power. Fine for top end and if you are flat chat on the track

Cats help with back pressure as well as regulating flow so you might find it better on the road as more torque.

Also if that car was not mapped with the old exhaust on it might be better on fuel too . Was it running rich?

It runs very rich.

Any recommendations on getting it re-mapped?

Or just see how it drives? The current vin data in the DME ECU is from an Orange 2007 GT3-RS. Bonkers but true.

nice!!

Top gear work and welding is sublime. as my garage guy said it looks like it would survive several nuclear holocausts. seems a shame to put in on the car and discolour too Wink

I would put the CATs and pipes on, let is settle in and see what you think. are you keeping the same back boxes? its running rich as there is no cats in there and it should have been re mapped to account for that. it might be a standard set up and the ECU should recognise CATs and adjust the mixture a bit. depends what you want from it all and how much $$ you want to chuck at it.

it will drive better as a road car with the extra torque and back pressure and not drone too I would imagine. that X pipe is supposed to be a bit more of a screamer up the top end than the normal shape ones.

remapping wise there is only one place to go for German cars - Chipwizards and the legend that is Wayne Schofeld!! look him up on facebook.

Thanks guys. Will check them guys out for a re-map if necessary.

Managed to get the Designtek silencer off the drivers side tonight. It’s tiny.

Oxygen sensors look like they might not want to come out. Hmmm.

Its not unusual to have to replace the o2 censors mate the slightest knock can damage them Thumb

Parts arriving now for project Spa exhaust.



Should be able to do some prep this weekend and aiming to do the majority of the welding next Friday afternoon.

Final tailpipe welding will have to be done at home. Missus is going love me welding in the garage.

Ok. So. Tonight’s adventures included an angle grinder, Dremmel disc & grinding stone and not to forget the chisel.

2 bloody hours to get 2 bolts out. But I didn’t give up.

Oh. And here’s my last Porsche mug. Honest.



Nut seized, rounded off & mild steel bolt seized to the mild steel tube. Wow! What do they expect will happen. Both bolts seized to the spacer tubes.

Going to redesign this spacer tube idea. Thinking of a stainless rod with a thread at each end. Then a stainless bolt from above & below. No way a Long front silencer bolt will go back in the front mount without removing the Designtek headers.



Grinding a flat on the rotten nut so I could get a purchase. Impact gun on the other end did a good job.



Finally.



Cat bypass pipes hopefully coming off tomorrow. Then it’s oxygen sensor time. Can’t wait.

Will do.

Is it just me? Or do these cars look like 991/2’s with their bumpers off?

Starting to really dislike rusty bolts.

One bypass pipe off this morning. 2nd one after kids football match.



Had to hacksaw the last bolt. No access with the grinder.

Removing the bypass pipe has exposed the tandem pump.

Nice to see the ACP cover in tidy condition? No invoice for this in the file that came with the car but there are pump invoices.

Are there 2 tandem pumps on the engine?

only 1 tandem mate , its a good sign of the way the car had been looked after to see he fitted a new pump and ACP cover .

long bolt in upside down so the silencers can be removed without taking the bumper off. Yes, it can be done!

Today’s progress

Finally pre-fitted the X pipe. Impressed with the fit.



Designtek flexi joint on it’s last legs. No longer needed. Thankfully.



Stainless centre exit section will be salvaged and is in good condition.



Gundo hack valve will go here.



Centre exit mock up.
