I've searched and read a couple post about the benefits of mods. But my question is, on the company parts offered from. I've seen headers for $79 -$299 and pulleys for $75 and up! With the headers can I buy an OBX or a similar $75 set

And they look the same as I know many companies knock off the original design. I've read that they perform the same too. My hard pipes were supposed to be Injen (the previous owner had them and paid for Injen but they are clearly not) but they work and look nice. Xpipe $29 is to be magnaflow $120 but it wasn't so I bought from them and honestly It's the same result/look/sound... So under there guarantee it's going back(yes they stand behind their promise!)..

 

Does anyone here have experience with a less expensive company and have you had or know of any issues with the product? On another forum a company AMS is getting torched for horrible customer service and selling inferior knockoffs parts. Any experience on them here? Been tempted to get their pulley since I've had great success with gains/response from pulleys on others cars but I've read

on a NA its a shot in the dark on balancing, etc. any experiences?

 

Also TESTPIPE or NOT... Is my 100 cel cat enough or go back to the 2 glass packs and delete the cats? What benefit does testpipe have on NA Z32 engine? I've had them on other cars including the TT we had but not a NA?

AMS are seemingly well-known for letting other firms do all the R&D work, and then getting their "local exhaust manufacturers" (Far East, apparently) to replicate things and sell them for a lower price. Quality is apparently quite hit and miss with them.

 

That said, I've just splashed out on a apir of AMS 3" expansion downpipes, which are a replica of Speciality Z's own design which are about double the price. On inspection, all the welds look decent and all the flage holes look to be in the right positions. :)

 

My Zed's not going to be about extracting every last possible ounce of power, so I don't need "the best downpipes in the world" for it - I just wanted some that would make good use of both the standard turbos and the upgraded ones I'll have in the future.

 

In an ideal world, I'd have bought Speciality Z downpipes, but my budget simply didn't allow for them. The ones I have bought look to be of decent quality though, so I'm happy with them at the moment. They'll be fitted (along with a full custom system) by the end of this month so I'll be able to report then on whether there were any fitment or alignment issues.

Thanks for your honest assessment. I'm not sure if I should put pulleys on the NA or just stick with the headers and once I install the HKS ALC get the ecu upgrade & just enjoy the Z32 as she is...

Update: the eBay headers arrived and they actually look good... I'm taking it to the shop Monday or Tuesday to get the actual thickness of the material tested from my exhaust shop. I did the leak test and both passed with each one having good looking welds. I may let my shop advise me on the best set (I will not tell them the cheaper set until they tell me their opinion) to install.
