Welcome to Neco.
I wouldnt suggest betting a tip alone or a muffler and getting it welded on. My friend did that to his Cougar in town and it sounded like your typical honduh crx. I would go with a Trubendz exhaust system. Also you also want to think about going strictly cosmetics...it isnt really cheap. Ive sunk a ton of money into cosmetics and upkeep. My car is in the shop again currently getting some things resprayed for the winter. Next year I will probably need to get the car repainted, thats just how things go. If you with performance, even though you have an ATX, things will still bring you more HP, which is a good thing. No you may not be able to beat the MTX GT Stang next to you, but not a lot of folks on this board can, BUT it will make a difference in other races. Either way you go, you wont really want to stop after one or two things. It becomes an addiction :rofl:
If you need any help or advice later on , feel free to PM me anytime you wish.
Thanks,
George
